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.

NOVOSENSE Launches NSIP3266 Full-Bridge Transformer Driver with Integrated Crystal Oscillator, Simplifying Isolated Driver Power Supply Design

　　NOVOSENSE today announced the launch of the NSIP3266 full-bridge transformer driver with integrated crystal oscillator, multiple protection functions and soft start support, which can be widely used in isolated driver power supply circuits in automotive on-board chargers (OBCs), traction inverters and charging piles, photovoltaic power generation and energy storage, server power supply and other systems. NSIP3266 supports a full-bridge topology with a wide range of inputs, and with clever pin and function design, it greatly simplifies the design of isolated driver’s power supply circuits, facilitating system manufacturers to optimize system circuits and shorten product time to market.　　Currently, isolated driver's power supply in high-voltage systems is available in three architectural forms: centralized, fully distributed, and semi-distributed. Centralized architecture has only one stage of power supply, and the auxiliary power input voltage has a wide input range, requiring closed-loop operation. At the same time, the transformer design is complicated, and especially when a single low-cost isolated power supply is used, there are problems of multi-output load regulation and long wiring, which increase the difficulty of system design and debugging.　　Fully distributed architecture uses independent isolated power modules to supply power to isolated drivers. The advantage is that 1-to-1 power supply and targeted protection can be achieved for isolated drivers, but a corresponding number of isolated power modules need to be configured, and the system cost is high.　　Semi-distributed architecture adopts a balanced strategy. Through a two-stage auxiliary power architecture, the first stage uses devices with a wide input voltage range to generate regulated rails, and the second stage can be a compact open-loop form using other devices to provide isolated power supply for isolated drives. Semi-distributed architecture is gaining popularity among engineers because of its simplicity in design and balance of system cost, performance, and protection requirements.　　Simplified circuit design with full-bridge topology　　NOVOSENSE's NSIP3266 full-bridge transformer driver is designed for semi-distributed architecture with isolated driver power supply. Common topology options for semi-distributed architecture include push-pull, LLC, and full-bridge. NSIP3266 adopts full-bridge topology. Compared with other solutions, the principle of full-bridge topology is simple, the transformer structure does not require a center tap, the working principle does not involve the design and selection of external L and C, and the peripheral BOM is often minimal. At the same time, the full-bridge topology is more tolerant to transformer design, including leakage inductance and parasitics, which saves engineers' efforts in system design and debugging.　　Ingenious design releases MCU resources　　It is worth mentioning that NSIP3266, through the internal integrated crystal oscillator circuit and RT pin design, allows engineers to complete the switching frequency configuration with only external resistors, achieving decoupling of MCU control and more flexible layout. At the same time, it can still provide safe power supply when the MCU fails, promoting higher system safety. In addition, the built-in soft-start function of NSIP3266 also eliminates the need for MCU control. While not requiring MCU domain routing, it saves secondary-side current limiting resistors, greatly simplifying board design and improving architectural flexibility.　　Wide voltage input and comprehensive protection　　NSIP3266 supports a wide operating voltage range of 6.5V~26V. No additional TVS protection tube is required in the system circuit, allowing engineers to choose the pre-stage power supply more flexibly. In addition, NSIP3266 provides multiple protection functions, including undervoltage protection, overcurrent protection, over-temperature protection, etc. The comprehensive protection functions enable engineers to focus on the optimization and innovation of the core system functions, and to design the system quickly and efficiently to meet the reliability requirements.　　Packaging and selections　　NSIP3266 is available in EP-MSOP8 package (3.0 x 3.0mm x 0.65mm, with thermal pad). The industrial version, NSIP3266-D, and the automotive version, NSIP3266-Q1, which meets the requirements of AEC-Q100, will be mass-produced in the first half of 2025. Please contact NOVOSENSE's sales team (sales@novosns.com) for product details or to request samples.　　Rich isolation products meet diverse needs　　With its expertise and leadership in isolation technology, NOVOSENSE provides a series of isolation and "isolation+" products covering digital isolators, isolated sampling, isolated interfaces, isolated power supply, and isolated drivers. NSIP3266 is a new addition to NOVOSENSE's isolated power supply family.

NOVOSENSE's NCA1044-Q1 CAN Transceiver Successfully Passes the IBEE/FTZ-Zwickau EMC Certification

　　NOVOSENSE announced that its newly launched NCA1044-Q1, an automotive-grade CAN transceiver, had received the EMC certification test reports from IBEE/FTZ-Zwickau, a prestigious European testing organization. NCA1044-Q1 successfully passed all test items. NOVOSENSE now can provide the test report to support automakers in streamlining their system certification process and accelerating their product launches.　　CAN transceivers are commonly used in automotive CAN bus networks typically for critical control and diagnostics functions, such as battery, motor control, electronic control, braking, steering, and airbag systems. These applications are prone to various sources of electromagnetic interference (EMI), including battery, motor and electronic control systems for EVs, engine, frequency converter and wireless communication devices. Such disturbances can adversely affect data transmission, leading to signal errors or system failures, and even compromised system safety.　　In addition, due to the long distance of CAN bus wiring in automotive systems, CAN transceivers can easily radiate noise through the CAN bus acting as an antenna. This can result in radiated emission and conducted emission from modules or the entire system that exceed the requirements for vehicle. Therefore, CAN transceivers that provide good electromagnetic compatibility (EMC) performance are essential for ensuring system reliability.　　Full compliance with IBEE/FTZ-Zwickau certification　　Given the critical role of CAN transceiver's EMC performance in automotive safety, countries or regions have established stringent automotive EMC standards and certification procedures for automakers to follow. For example, both the SAE J2962 standard and the European IBEE/FTZ-Zwickau certification set clear requirements for the EMC performance of automotive electronics.　　The IBEE/FTZ-Zwickau certification is carried out according to the IEC 62228-3 standard. Compared with SAE J2962, IEC 62228-3 excludes the effects of peripheral circuits, focuses more on the EMC property of the CAN transceiver itself, and specifies higher performance level requirements. The IEC 62228-3 standard is also extensively adopted by automakers outside of Europe. The IBEE/FTZ-Zwickau certification includes four tests: Emission RF Disturbances, Immunity RF Disturbances, Immunity Transients, and Immunity ESD. NCA1044-Q1 from NOVOSENSE successfully passed all four tests.　　Industry-leading interference immunity　　NCA1044-Q1 features an ingenious circuit design that addresses the issue of output signal errors caused by abnormal high-voltage interference affecting its output circuit. This enhances its EMC performance, helping customers substantially reduce their EMC design complexity, simplify peripheral components, and lower costs.　　Furthermore, NCA1044-Q1 boasts industry-leading interference immunity. According to IEC 62228-3, when external RF noise at different frequency bands couples to the CAN bus, a higher pass-through power indicates stronger interference immunity. This means a lower risk of errors in the system.　　Even without the use of a common-mode inductor filter on the bus, NCA1044-Q1 from NOVOSENSE can still meet the highest power requirements specified in the standard (as shown in Figure-1 and Table-2). Although this test is typically not required at the application level, NCA1044-Q1 still successfully passed the test. This capability helps users reduce peripheral circuits, lower costs, and enhance system robustness.　　Packages and selection　　NCA1044-Q1 is now in mass production and is available in SOP8 and DFN8 packages. Compliant with the AEC-Q100 Grade 1 requirements, it operates in a wide temperature range from -40°C to 125°C, and provides over-temperature protection. NCA1044-Q1 also supports TXD dominant timeout function and remote wake-up in standby mode.
