ROHM has Developed Ultra-Compact CMOS Op Amp: Delivering Industry-Leading* Ultra-Low Circuit Current

　　ROHM’s ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry’s lowest operating circuit current. This IC is optimized to be applied as a measurement sensing amplifier in size-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors.　　As the demand continues to grow for more sophisticated control in battery-driven devices, the importance of sensors that detect parameters such as temperature, humidity, vibration, pressure, and flow rate – along with the op amps used to amplify these sensor signals – continues to rise. At the same time, greater miniaturization and energy savings in applications is a necessary step to realizing a sustainable society –placing similar demands on individual devices as well.　　In response to these evolving market needs, ROHM has advanced its process, packaging, and proprietary Nano Energy™ circuit technologies to develop an op amp that addresses three key requirements: lower power consumption, higher accuracy, and compact size. The newly developed TLR1901GXZ achieves an ultra-compact footprint of less than 1mm2 by adopting a WLCSP (Wafer Level Chip Scale Package) with a fine ball pitch of 0.35mm while delivering an industry-leading low operating current of 160nA (typ.). This not only contributes to high-density mounting in space-constrained applications, but also to a significantly extended battery life.　　Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. This represents an approximate 45% reduction compared to typical products on the market. A maximum input offset voltage temperature drift of 7uV/°C ensures high accuracy operation over the operating temperature range.　　Design flexibility can be further enhanced by pairing the op amp with ROHM’s ultra-compact general-purpose resistors, such as the MCR004 (0402 metric / 01005 inch) and MCR006 (0603 metric / 0201 inch), for applications like gain adjustment. The MCR004 series lineup includes the MCR004E –an environmentally friendly, fully lead-free option designed to support sustainable designs. Adapter boards featuring SSOP5 package ICs are offered as well to support initial evaluation and replacement assessments.　　Going forward, ROHM will continue to pursue further power savings in op amps by advancing both miniaturization and original ultra-low power technologies. At the same time, we are committed to improving device performance by reducing noise and offset, expanding power supply voltage ranges, and contributing to solving social issues through more precise application control.　　Key Product Characteristics　　Application Examples　　• Consumer devices: wearables, smart devices, motion sensors, etc.　　• Industrial equipment: gas detectors, fire alarms, handheld measurement instruments, environmental sensors for IoT, etc.　　Online Sales Information　　Sales Launch Date: Now　　Pricing: $2.1/unit (samples, excluding tax)　　Online Distributors: AMEYA360　　• Applicable Part No: TLR1901GXZ-E2　　• IC-Mounted Adapter Board: TLR1901GXZ-EVK-001　　What is Nano Energy™ Technology?　　Nano Energy™ refers to proprietary ultra-low current consumption technology that achieves a current consumption on the order of nano ampere (nA) by combining advanced analog technologies covering circuit design, layout, and processes utilizing ROHM’s vertically integrated production system.　　This contributes not only to extending operating time of battery operated IoT and mobile devices, but also improving efficiency in industrial and automotive equipment where increased power consumption is problematic.　　https://www.rohm.com/support/nano 　　Nano Energy™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　WLCSP (Wafer Level Chip Scale Package)　　An ultra-compact package in which terminals and wiring are formed directly on the wafer before separated into individual chips. Unlike general packages where the chips are cut from wafers and then molded with resin to form terminals, WLCSP allows the package size to match the chip itself, making it possible to further reduce size.　　Input Offset Voltage　　The small voltage difference that must be applied between the inverting and non-inverting inputs of the operational amplifier to make the output voltage exactly zero.　　Input Offset Voltage Temperature Drift　　Refers to how much an op amp's input offset voltage changes as the temperature changes.

ROHM’s SiC MOSFETs Adopted in Schaeffler’s Inverter Brick, Now in Mass Production

　　ROHM and Schaeffler, a leading German automotive supplier, have started mass production of a new high-voltage inverter brick equipped with ROHM’s SiC (silicon carbide) MOSFET bare chips as part of their strategic partnership. The inverter brick is intended for a major Chinese car manufacturer.High voltage inverter brickSiC MOS Wafer　　The Schaeffler inverter subassembly is the essential power device building block (brick) to control the electric drive via logic signals. This is where the high-frequency current pulses are produced that set the vehicle’s electric motor in motion. The performance characteristics of the inverter brick now being produced are impressive: Schaeffler increased the output of the brick by increasing the maximum possible battery voltage to much more than the usual 800 V – and with RMS currents of up to 650 A, which turn the sub-module into a compact power pack.　　“Through our strategic approach of incorporating scalability and modularity into our e-mobility solutions – from individual components to a highly integrated electric axle – we developed the readily integrated inverter brick. Based on our generic platform development, it took us just one year to bring this optimal product for the popular X-in-1 architectures to volume production readiness,” says Thomas Stierle, CEO of the E-Mobility Division at Schaeffler.　　Modularity and scalability as the key to easy integration　　As a core component of an inverter, a brick has to meet strict requirements. The characteristics of the sub-module are indicative of the factors behind the current sales success and start of volume production: ROHM’s silicon carbide (SiC) power semiconductors enable the frame-mounted sub-module with high power density to be compact, efficient, and readily integrated into various inverters through its modular and scalable design. The sub-module incorporates the power module for pulse width modulation (PWM) of the current pulses, the DC link capacitor, a DC link and a cooler. Moreover, the brick has a DC boost function, thanks to which a vehicle with 800 V architecture can also be charged at a 400 V charging station at a charging speed of 800 V.　　“We are glad about the launch of volume production for Schaeffler’s inverter brick with our 4th generation SiC MOSFET,” says Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM. “With our SiC technology we are making a substantial contribution to increasing the efficiency and performance of electric cars. Working with Schaeffler as our partner, we are thus fostering innovation and sustainability in the automotive industry,” Dr. Ino adds.　　The strategic partnership of Schaeffler (originally initiated under Vitesco Technologies) with ROHM has existed since 2020 and serves to secure capacity for energy-efficient SiC power semiconductors.Thomas Stierle, CEO E-Mobility Division at Schaeffler (left) and Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM　　About Schaeffler Group　　The Schaeffler Group has been driving forward groundbreaking inventions and developments in the field of motion technology for more than 75 years.

Adapting to challenging magnetic environments: MT73xx 3D dual-output Hall latches from NOVOSENSE enable precise automotive motor control

　　The NOVOSENSE MT73xx series dual-output Hall latches, based on 3D Hall technology, support SS (Speed & Speed) or SD (Speed & Direction) dual-channel outputs and complies with Automotive Grade 0 standards. Ideal for motor control systems such as power windows, liftgates, and sunroofs, this product family enhances the accuracy and stability of speed and position detection, optimizing overall in-vehicle comfort.　　In motor control systems, precise detection of speed and direction signals directly influences system response speed and operational stability. Traditional solutions typically rely on a combination of two separate Hall latches, requiring high magnetic ring installation precision. This often leads to issues such as signal phase deviation, poor synchronization, and structural complexity.　　Integrates a 3D Hall sensing structure with inherent orthogonal output characteristics, the MT73xx series can simultaneously deliver dual-channel speed signals (SS output) with a 90° phase difference or speed and direction signals (SD output), making it widely suitable for “speed-direction” detection applications. This design reduces dependency on precise positioning of magnetic poles, mitigates dual-channel phase deviation, simplifies system architecture, and improves overall system stability, providing a more flexible and reliable solution for motion control detection.　　Compatibility with diverse magnetic ring configurations enabled by VHS technology　　To achieve high-precision 3D sensing, the MT73xx series adopts NOVOSENSE’s proprietary VHS (Vertical Hall Sensor) technology. Through combinations of XY, YZ, and XZ axial sensing, any two axes naturally deliver orthogonal outputs, enhancing signal synchronization.　　Additionally, the MT73xx series offers excellent compatibility with various magnetic ring configurations – whether axial, radial, or irregularly shaped magnets – maintaining robust duty cycle performance. This allows customers to adapt designs flexibly depending on magnetic ring characteristics and installation environments, further reducing development complexity and tuning costs.　　Dual-output design for optimized system integration　　Regarding system integration, the MT73xx’s dual-output capability allows it to replace traditional single- or dual-Hall solutions by directly transmitting SS (Speed & Speed) or SD (Speed & Direction) signals to ECU, minimizing the requirements for peripheral redundant position sensors.　　This approach not only saves PCB space and simplifies structural layouts, but also enhances solution integration, offering greater design flexibility for innovative applications in motor control and intelligent cockpit systems.

High-voltage half-bridge driver NSD2622N from NOVOSENSE: A high-reliability, high-integration solution tailored for E-mode GaN

　　NOVOSENSE has launched NSD2622N, a high-voltage half-bridge driver IC specifically designed for enhancement-mode GaN (E-mode GaN). This chip integrates positive/negative voltage regulation circuits, supports bootstrap supply, and provides high dv/dt immunity and robust driving capability. It significantly simplifies GaN driver circuit design while enhancing system reliability and reducing overall costs.　　Application background　　In recent years, gallium nitride high-electron-mobility transistors (GaN HEMTs) are gaining increasingly widespread adoption in high-voltage, high-power applications, such as AI data center power supplies, microinverters, and on-board chargers (OBCs). With significant advantages of high switching frequency and low switching losses, GaN HEMTs enable substantially improved power density in power supply systems, noticeably optimized energy efficiency, and significantly reduced system costs.　　However, GaN devices still face challenges in real-world applications. For instance, E-mode GaN devices exhibit low turn-on thresholds. In high-voltage and high-power applications, particularly in hard-switching operation mode, poorly designed driver circuits can lead to false triggering due to crosstalk during high-frequency high-speed switching. Additionally, the complexity of compatible driver circuit designs raises the barrier to GaN device adoption.　　To accelerate widespread GaN adoption, leading GaN manufacturers at home and abroad have introduced some power ICs with integrated drivers, especially MOSFET-LIKE GaN power devices in Si-MOSFET-compatible packages, which somewhat reduce GaN driver circuit design complexity. However, driver-integrated GaN solutions have limitations: they struggle to meet customized design requirements and are unsuitable for applications adopting multi-device parallel or bidirectional switching topologies. Therefore, discrete GaN devices with dedicated drivers remain essential for many applications. To address the above-mentioned limitations, NOVOSENSE has developed NSD2622N – a driver IC tailored to E-mode GaN, aiming to deliver high-performance, high-reliability, and cost-competitive driving solutions for high-voltage and high-power GaN applications.　　Product features　　NSD2622N is a high-voltage half-bridge driver IC specifically designed for E-mode GaN. It integrates a voltage regulation circuit capable of generating a configurable stable positive voltage from 5V to 6.5V to ensure reliable GaN driving, as well as a charge pump circuit that produces a fixed -2.5V negative voltage for reliable GaN turn-off. By integrating both positive and negative voltage regulation circuits, the chip supports high-side output with bootstrap supply.　　NSD2622N leverages NOVOSENSE’s proven capacitive isolation technology. Its high-side driver withstands a voltage range of -700V to +700V and a minimum SW dv/dt immunity of 200V/ns. Meanwhile, low propagation delay and tight delay matching between high-side and low-side outputs make it a perfect match for the high-frequency, high-speed switching requirements of GaN devices. Additionally, NSD2622N delivers 2A (source) and -4A (sink) peak drive currents on both high-side and low-side outputs, meeting the requirements of high-speed GaN driving and multi-device parallel configurations. The IC also includes an integrated 5V LDO that can power circuits like digital isolators in applications requiring isolation.　　Key specifications of NSD2622N　　SW voltage range: -700V to 700V　　SW dv/dt immunity: > 200V/ns　　Wide supply voltage range: 5V-15V　　Adjustable positive output voltage range: 5V-6.5V　　Built-in negative output voltage: -2.5V　　Peak drive current: 2A (source) / 4A (sink)　　Minimum input pulse width (typical): 10ns　　Input-to-output propagation delay (typical): 38ns　　Pulse width distortion (typical): 5ns　　Rise time (1nF load, typical): 6.5ns　　Fall time (1nF load, typical): 6.5ns　　Built-in dead time (typical): 20ns　　Bootstrap supply for high-side output　　Integrated 5V LDO for digital isolator supply　　Undervoltage lockout (UVLO) and overtemperature protection　　Operating temperature range: -40°C to +125°CFunctional block diagram of NSD2622N　　Eliminating false triggering risks and providing more stable drive voltage　　Compared to conventional Si MOSFET driver solutions, the key challenge in E-mode GaN driver circuit design lies in providing appropriate, stable and reliable positive/negative bias voltages. This is because that E-mode GaN typically requires a 5V-6V turn-on voltage, while its threshold voltage is as low as 1V, or even lower at high temperatures, necessitating negative turn-off voltage to prevent false triggering. To address this challenge, two common drive solutions are used for E-mode GaN: resistive-capacitive (RC) voltage division drive and direct drive.　　1. RC voltage division drive　　This approach utilizes standard Si MOSFET driver ICs. As shown in the diagram, during turn-on, the parallel combination of Cc and Ra is connected with Rb in series, dividing the driver supply voltage (e.g., 10V) to provide a 6V gate drive voltage for the GaN device, with Dz1 clamping the positive voltage. During turn-off, Cc discharges to provide negative turn-off voltage for the GaN device, with Dz2 clamping the negative voltage.RC voltage division drive solution　　Although the RC voltage division circuit does not require sophisticated driver ICs, it introduces additional parasitic inductance due to a large number of components involved, which can impact GaN’s switching performance at high frequencies. Moreover, since the negative turn-off voltage relies on discharge from capacitor Cc, the negative turn-off voltage proves unreliable.　　As shown in the half-bridge demo board test waveforms, during the startup phase (T1 in the waveform), the absence of initial charge on Cc results in failure to establish negative voltage and thus zero-voltage turn-off; during the negative turn-off period following the driver’s signal transmission (T2), the negative voltage amplitude fluctuates with capacitor discharge; and during the prolonged turn-off period (T3), the capacitor cannot sustain negative voltage, eventually discharging to zero. Consequently, RC voltage division circuits are generally limited to medium/low power applications with relatively lower reliability requirements, and are proved unsuitable for high-power systems.Waveform of E-mode GaN using RC voltage division drive circuit(CH2: Drive supply voltage; CH3: GaN gate-source voltage)　　2. Direct drive　　The direct drive solution requires selecting a driver IC with an appropriate undervoltage-lockout (UVLO) threshold, for example, NSI6602VD, which is specifically designed for E-mode GaN with a 4V UVLO threshold. When paired with an external positive/negative voltage regulation circuit, it can directly drive E-mode GaN devices. Below is a typical application circuit.NSI6602VD driver circuitPositive and negative voltage regulation circuits　　This direct drive solution can provide reliable negative turn-off voltage for GaN under all operating conditions, when the auxiliary power supply is functioning normally. As a result, this approach is widely adopted in various high-voltage, high-power GaN applications.　　The next-generation GaN driver NSD2622N from NOVOSENSE, integrates the positive/negative voltage regulation circuits directly into the chip. As shown in the half-bridge demo board test waveforms below, NSD2622N maintains consistent negative turn-off voltage amplitude and duration regardless of operating conditions. Specifically, during startup (T1 in the waveform), the negative voltage is established even before the driver sends signals; during GaN turn-off (T2), the negative voltage remains stable in amplitude; during extended periods without driver signals (T3), the negative voltage continues to stay reliably stable.Waveforms of E-mode GaN using NSD2622N driver circuit(CH2: Low-side GaN Vds, CH3: Low-side GaN Vgs)　　Simplified circuit design and reduced system costs　　NSD2622N can provide stable and reliable direct drive for GaN devices. More importantly, by integrating positive/negative voltage regulators, it significantly reduces external component count. By adopting the bootstrap supply architecture, NSD2622N greatly simplifies driver power circuit design and lowers overall system costs.　　Taking a 3kW power supply unit (PSU) as an example, assuming both phases of the interleaved TTP PFC and full-bridge LLC use GaN devices, a complexity comparison between two direct-drive solutions is given below:　　When using the NSI6602VD driver solution, each half-bridge high-side driver requires an independent isolated power supply in conjunction with corresponding isolation and positive/negative voltage regulation circuits. This means complex auxiliary power supply design for isolation. Given the high power quality requirements of GaN driving and the fact that the main power paths of the PFC and LLC stages are typically placed on separate boards, a two-stage auxiliary power architecture is often necessary. In this configuration, the first stage typically employs a device with wide input voltage range like flyback converter, to generate regulated voltage rails. The second stage may use an open-loop full-bridge topology to provide isolated power and further regulate the power to generate the required positive and negative supply voltages for NSI6602VD. Below is a typical power architecture for such a driver solution.Typical power architecture for NSI6602VD driver solution　　The NSD2622N driver solution significantly simplifies auxiliary power design through its bootstrap supply capability. Below is a typical power architecture for this approach.Typical power architecture for NSD2622N driver solution　　A detailed comparison of bill-of-materials (BOM) for driver and power supply circuits between the above-mentioned two GaN direct-drive solutions is provided in the table below. It can be seen that the NSD2622N solution utilizing bootstrap supply, dramatically reduces total component count compared to the NSI6602VD’s isolated power supply approach, resulting in substantially lower system costs. Even in applications requiring isolated power supply, NSD2622N maintains its competitive edge - its integrated positive/negative voltage regulators enable a more simplified peripheral circuit relative to the NSI6602VD solution, leading to fewer components and lower system costs.BOM comparison between two GaN direct drive solutions　　Versatile GaN compatibility and flexible drive voltage adjustment　　The E-mode GaN driver IC NSD2622N from NOVOSENSE delivers not only superior performance but also broad compatibility across various GaN devices from different brands, of different types (including both voltage-mode and current-mode), and at different voltage ratings. For instance, the output voltage of NSD2622N can be set between 5V to 6.5V by adjusting feedback resistors. This enables selection of the most appropriate driving voltage for any GaN device by simply adjusting the feedback resistors to match specific GaN characteristics, allowing GaN devices from different brands to operate at their individual peak performance points.　　In addition, NSD2622N features a minimum dv/dt immunity of 200V/ns on the switching node (SW), enhancing the upper limit of GaN switching speed. The adoption of a more compact QFN package and the design of independent turn-on and turn-off output pins further reduce the driver loop parasitic inductance. The over-temperature protection ensures safer GaN applications.　　NOVOSENSE also offers single-channel GaN driver IC NSD2012N. Featuring 3mm*3mm QFN package and adjustable negative voltage capability, it can meet more personalized application requirements.

ROHM Develops an Ultra-Compact MOSFET Featuring Industry-Leading* Low ON-Resistance Ideal for Fast Charging Applications

　　ROHM has developed a 30V N-channel MOSFET — AW2K21 — in a common-source configuration that achieves an industry-leading ON-resistance of 2.0mΩ (typ.) in a compact 2.0mm × 2.0mm package.　　With the rise of compact devices featuring large-capacity batteries, such as smartphones, the need for fast charging functionality to shorten charging times continues to grow. These applications require bidirectional protection to prevent reverse current flow to peripheral ICs and other components when not actively supplying or receiving power. What’s more, fast charging involves high current power transfer, leading smartphone manufacturers to demand stringent specifications for MOSFETs, including a maximum current rating of 20A, breakdown voltage between 28V and 30V, and an ON-resistance of 5mΩ or less. However, meeting these requirements with standard solutions typically necessitates the use of two large low ON-resistance MOSFETs, increasing board space along with mounting complexity.　　In response, ROHM developed an ultra-compact low ON-resistance MOSFET optimized for fast high-power charging. The AW2K21 adopts a proprietary structure that enhances cell density while minimizing the ON-resistance per unit chip area. Two MOSFETs are integrated into a single package, allowing a single part to support bidirectional protection applications (commonly required in power supply and charging circuits).　　The proprietary structure also places the drain terminal on the top surface, unlike on the backside in standard vertical trench MOS structures. This enables the use of a WLCSP, which achieves a larger chip-to-package area ratio that further reduces ON-resistance per unit area. As a result, the new product not only minimizes power loss but also supports high current operation, making it ideal for high-power fast charging applications despite its ultra-compact size.　　For example, in power supply and charging circuits for compact devices, standard solutions typically require two 3.3mm × 3.3mm MOSFETs. In contrast, the AW2K21 can achieve the same functionality with a single 2.0mm × 2.0mm unit, reducing the footprint and ON-resistance by approximately 81% and 33%, respectively. Even compared to similarly sized GaN HEMTs, ON-resistance is decreased by up to 50%, contributing to lower power consumption and increased space savings across a variety of applications.　　The AW2K21 is also suitable for use as a unidirectional protection MOSFET in load switch applications, where it maintains the industry’s lowest ON-resistance. At the same time, ROHM is further pushing the limits of miniaturization with the development of an even smaller 1.2mm × 1.2mm model.　　Going forward, ROHM remains dedicated to supporting the miniaturization and energy efficiency of electronic systems through compact, high-performance solutions that contribute to the realization of a sustainable society.　　Key Product Characteristics　　Application Examples　　• Smartphones　　• VR (Virtual Reality) headsets　　• Compact printers　　• Tablets　　　　 • Wearables　　　　　　　　　　 • LCD monitors　　• Laptops　　　　 • Portable gaming consoles　　　 • Drones　　And other applications equipped with fast charging capability.　　Terminology　　MOSFET (Metal Oxide Semiconductor Field Effect Transistor)　　A field-effect transistor (FET) featuring a metal oxide semiconductor structure (the most commonly used type). It consists of three terminals: gate, drain, and source. Applying a voltage to the gate (control terminal) regulates current flow from the drain to the source.　　N-channel MOSFETs turn ON when a positive voltage is applied to the gate relative to the source. A common-source configuration MOSFET integrates two transistor elements that share a single source terminal.　　ON-Resistance　　The resistance between the Drain and Source of a MOSFET when it is in the ON state. A smaller RDS(on) reduces power loss during operation.　　Breakdown Voltage　　The maximum voltage that can be applied between the drain and source terminals of a MOSFET without causing damage. Exceeding this limit results in dielectric breakdown, potentially leading to device failure or malfunction.　　WLCSP (Wafer Level Chip Scale Package)　　An ultra-compact package in which terminals and wiring are formed directly on the wafer before separated into individual chips. Unlike general packages where the chips are cut from the wafer and then molded with resin to form terminals, WLCSP allows the package size to match the chip itself, making it possible to further reduce size.　　GaN HEMT　　GaN (Gallium Nitride) is a compound semiconductor material used in next-generation power devices. It offers superior physical properties over conventional silicon, enabling higher frequency operation with faster switching speeds. HEMT stands for High Electron Mobility Transistor.

ROHM Introduces a New MOSFET for AI Servers with Industry-Leading* SOA Performance and Low ON-Resistance

　　ROHM has released of a 100V power MOSFET - RY7P250BM - optimized for hot-swap circuits in 48V power systems used in AI servers and industrial power supplies requiring battery protection to the market.　　As AI technology rapidly advances, data centers are facing unprecedented processing demands and server power consumption continues to increase annually. In particular, the growing use of generative AI and high-performance GPUs has created a need to simultaneously improve power efficiency while supporting higher currents. To address these challenges, the industry is shifting from 12V systems to more efficient 48V power architectures. Furthermore, in hot-swap circuits used to safely replace modules while servers remain powered on, MOSFETs are required that offer both wide SOA (Safe Operating Area) and low ON-resistance to protect against inrush current and overloads.　　The RY7P250BM delivers these critical characteristics in a compact 8080-size package, helping to reduce power loss and cooling requirements in data centers while improving overall server reliability and energy efficiency. As the demand for 8080-size MOSFETs grows, this new product provides a drop-in replacement for existing designs. Notably, the RY7P250BM achieves wide SOA (VDS=48V, Pw=1ms/10ms) ideal for hot-swap operation. Power loss and heat generation are also minimized with an industry-leading low ON-resistance of 1.86mΩ (VGS=10V, ID=50A, Tj=25°C), approximately 18% lower than the typical 2.28mΩ of existing wide SOA 100V MOSFETs in the same size.　　Wide SOA tolerance is essential in hot-swap circuits, especially those in AI servers that experience large inrush currents. The RY7P250BM meets this demand, achieving 16A at 10ms and 50A at 1ms, enabling support for high-load conditions conventional MOSFETs struggle to handle.　　ROHM’s new product has also been certified as a recommended component by leading global cloud platform provider, where it is expected to gain widespread adoption in next-generation AI servers. Especially in server applications where reliability and energy efficiency are mission-critical, the combination of wide SOA and low RDS(on) has been highly evaluated for cloud infrastructure.　　Going forward, ROHM will continue to expand its lineup of 48V-compatible power solutions for servers and industrial equipment, contributing to the development of sustainable ICT infrastructure and greater energy savings through high-efficiency, high-reliability products.　　Application Examples　　• 48V AI server systems and power supply hot-swap circuits in data centers　　• 48V industrial equipment power systems (i.e. forklifts, power tools, robots, fan motors)　　• Battery-powered industrial equipment such as AGVs (Automated Guided Vehicles)　　• UPS and emergency power systems (battery backup units)　　Online Sales InformationSales Launch Date: May 2025　　Pricing: $5.50/unit (samples, excluding tax)　　Online Distributors: DigiKey™, Mouser™ and Farnell™　　The products will be offered at other online distributors as they become available.　　Applicable Part No: RY7P250BM　　EcoMOS™ BrandEcoMOS™ is ROHM's brand of silicon MOSFETs designed for energy-efficient applications in the power device sector.　　Widely utilized in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS™ provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.　　TerminologyHot-Swap Circuit　　A circuit that enables components to be inserted or removed while the system remains powered on.　　It typically consists of MOSFETs, protection elements, and connectors, and is responsible for suppressing inrush current and protecting against overcurrent conditions, ensuring stable operation of the system and connected components.　　Power MOSFET　　A MOSFET designed for power conversion and switching applications. N-channel MOSFETs are the dominant type, turning on when a positive voltage is applied to the gate relative to the source. They offer lower ON-resistance and higher efficiency than P-channel variants. Due to their low conduction loss and high-speed switching performance, power MOSFETs are commonly used in power supplies, motor drives, and inverter circuits.　　SOA (Safe Operating Area)　　The defined range of voltage and current in which a device can operate reliably without risk of failure. Operating outside this boundary may result in thermal runaway or permanent damage. SOA is especially critical in applications exposed to inrush currents or overcurrent conditions.　　Low ON-resistance (RDS(on))　　The resistance value between the Drain and Source of a MOSFET during operation. A smaller RDS(on) reduces power loss during operation.　　Inrush Current　　A sudden surge of current that momentarily exceeds the rated value when an electronic device is powered on. Proper control of this current reduces stress on power circuit components, helping to prevent device damage and stabilize the system.
