ROHM’s Three-Phase Brushless DC Motor Gate Driver Achieving FET Heat Reduction while Suppressing EMI

　　ROHM has developed the “BD67871MWV-Z” three-phase brushless DC motor gate driver for medium voltage applications (12 to 48V systems). By incorporating ROHM’s proprietary gate drive technology TriC3™, it greatly reduces FET’s switching loss while maintaining low EMI – traditionally a trade-off in motor driver ICs.　　Motors account for approximately 60% of global electricity consumption, making control technology which affects energy efficiency, increasingly critical. In 12V to 48V motor drive applications, a simple configuration where an MCU controls three gate drivers has been the mainstream. However, in recent years, demands for high efficiency and precise control have grown, accelerating the adoption of solutions combining an MCU with an integrated three-phase motor driver. Further, a technical challenge in three-phase motor drivers has been the trade-off between “power consumption reduction” and “noise / EMI (electro-magnetic interference) reduction,”.　　BD67871MWV-Z features ROHM's proprietary Active Gate Drive technology “TriC3™”, which rapidly senses voltage information from the external power FETs and adjust gate drive current accordingly in real-time. This greatly reduces FETs’ switching loss (and hence heat generation) FET power consumption during switching while simultaneously suppressing ringing to achieve low EMI.　　Compared to ROHM's conventional constant-current drive products, TriC3™ gate drive has been demonstrated in actual motors that FET heat generation by approximately 35% while maintaining equivalent EMI levels. Furthermore, BD67871MWV-Z adopts UQFN28 package and pin layout which are commonly used in motor driver ICs for medium-voltage industrial equipment applications, contributing to reduced engineering effort required in circuit modifications and new designs.　　Mass production of the new product commenced in September 2025 (sample price: $5.5/unit, tax excluded).　　ROHM also offer general-purpose motor drivers (BD67870MWV-Z, BD67872MWV-Z) with the same package and pin configuration as the new product, designed for constant-voltage drive. From general-purpose types to the value-added types featuring the new TriC3™, we offer a comprehensive product lineup to supports a wide variety of applications and use cases. We are committed to contributing to improved motor efficiency, enhanced application functionality, and reduced power consumption.　　Application Examples　　•Industrial Equipment: Various motors such as electric drills/drivers and industrial fans　　•Consumer Appliances: Various motors used in vacuum cleaners, air purifiers, air conditioners, ventilation fans and E-bikes (electric-assist sports bicycles)　　TriC3™　　A multi-step constant current drive technology developed by ROHM. By controlling gate current in three steps, it achieves high-speed, high-efficiency operation while minimizing EMI by suppressing ringing.　　• TriC3™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　EMI (Electromagnetic Interference)　　EMI is used as an indicator of how much noise a product generates during operation, potentially causing malfunctions in surrounding ICs or systems. “Low EMI” means the product generates less noise.　　Ringing　　High-frequency oscillations or overshoot occurring during switching. This arises from the resonation between inductance and capacitance, including parasitic elements in the circuit. In the context of motor driving, ringing happens when the power MOSFETs are turned on and off.

ROHM Develops Breakthrough Schottky Barrier Diode Combining Low VF and IR for Advanced Image Sensor Protection

　　ROHM has developed an innovative Schottky barrier diode that overcomes the traditional VF / IR trade-off. This way, it delivers high reliability protection for a wide range of high-resolution image sensor applications, including ADAS cameras.　　Modern ADAS cameras and similar systems require higher pixel counts to meet the demand for greater precision. This has created a growing concern – the risk of damage caused by photovoltaic voltage generated under light exposure during power OFF. While low-VF SBDs are effective countermeasures, low IR is also essential during operation to prevent thermal runaway. However, simultaneously achieving both low VF and IR has been a longstanding technical challenge. ROHM has overcome this hurdle by fundamentally redesigning the device structure – successfully developing an SBD that combines low VF with low IR which is ideal for protection applications.　　The RBE01VYM6AFH represents a novel concept: leveraging the low-VF characteristics of rectification SBDs for protection purposes. By adopting a proprietary architecture, ROHM has achieved low IR that is typically difficult to realize with low VF designs. As a result, even under harsh environmental conditions, the device meets market requirements by delivering VF of less than 300mV (at IF=7.5mA even at Ta=-40°C), and an IR of less than 20mA (at VR=3V even at Ta=125°C.) These exceptional characteristics not only prevent circuit damage caused by high photovoltaic voltage generated when powered OFF, but also significantly reduce the risk of thermal runaway and malfunction during operation.　　The diode is housed in a compact flat-lead SOD-323HE package (2.5mm × 1.4mm / 0.098inch × 0.055inch) that offers both space efficiency and excellent mountability. This enables support for space-constrained applications such as automotive cameras, industrial equipment, and security systems. The RBE01VYM6AFH is also AEC-Q101 qualified, ensuring suitability as a protection device for next-generation automotive electronics requiring high reliability and long-term stability.　　Going forward, ROHM will focus on expanding its lineup with even smaller packages to address continuing miniaturization demands.　　Key Specifications　　Application Examples　　Image sensor-equipped sets such as ADAS cameras, smart intercoms, security cameras, and home IoT devices.　　Terminology　　Photovoltaic Voltage　　A term commonly used with optical sensors, referring to the voltage produced when exposed to light. In general, the stronger the light intensity or higher the pixel count the greater voltage generated.

ROHM has Developed New Smart Switches Optimized for Zonal Controllers

　　ROHM has developed six new high-side Smart Switches (Intelligent Power Devices, short: IPDs) BV1HBxxxEFJ series (BV1HB008EFJ-C, BV1HB012EFJ-C, BV1HB020EFJ-C, BV1HB040EFJ-C, BV1HB090EFJ-C, BV1HB180EFJ-C) with highly accurate current sensing capability and ON resistances from 9 mΩ to 180 mΩ. They are ideal for protecting loads and subsystems from abnormalities such as overcurrent, overvoltage, and overtemperature, ensuring reliable operation and safeguarding sensitive components in automotive lighting, body control such as, door locks and power windows. Extensive diagnostic capabilities, e.g., open load and reverse battery detection, further enhances safety and reliability.　　Vehicle electronic control systems are becoming increasingly sophisticated with the advancement of autonomous driving and electric vehicles (EVs). This evolution has heightened the importance of electronic protection from a functional safety standpoint, driving the shift toward Zonal Controllers architecture that manages vehicle functions in designated zones. As a result, the use of smart switches for electronic load protection and control is rapidly growing.　　Zonal controllers must each manage a large number of loads, but conventional smart switches often lack the drive capability required for high-capacitance loads. ROHM’s new smart switches address this challenge, delivering key performance attributes such as low ON resistance and high inductive energy clamp while significantly improving capacitive load drive capability. By commercializing high-performance smart switches tailored to zonal controllers’ requirements, ROHM is contributing to automotive electrification and the elimination of mechanical fuses.　　The new products feature exceptional high-capacitance load driving capability, maximizing performance at the critical interface between Zonal Controllers and output loads (including various ECUs). Leveraging proprietary cutting-edge process technology makes it possible to achieve both low ON resistance and high inductive energy clamp – two characteristics typically involve a trade-off. The result is a well-balanced integration of three key performance metrics: drive capability, ON resistance, and energy tolerance. This enhances system design safety, efficiency, and reliability. The devices also incorporate a best-in-class* high-precision current sensing function (±5%) that provides effective protection for harnesses connected to output loads. At the same time, the compact, high heat dissipation HTSOP-J8 package ensures excellent design versatility.　　Going forward, ROHM remains committed to improving safety, security, and energy efficiency in the automotive field by continuing to develop high reliability, high performance devices.　　*ROHM study on high-side Smart Switches - September 30th, 2025　　Application Examples　　Body applications, powertrain/inverter systems, other switch-related circuits　　Terminology　　Zonal Controllers　　An emerging design concept in automotive electronic architecture, zonal controllers represent a shift away from the conventional approach of assigning dedicated ECUs for each function, such as lighting, door locks, and power windows. Instead, the vehicle is divided into zones, with a zonal controller manages multiple functions in its zone.　　Intelligent Power Devices (IPD) / Smart Switches　　Smart power switches are semiconductor devices that electronically control the delivery of power by turning it on and off, while also providing integrated protection and diagnostic features such as overcurrent, overvoltage, thermal shutdown, current sensing, and open load detection to enhance system reliability and safety.　　Capacitive Load Driving Capability　　A technical term referring to the ability of an electronic circuit or semiconductor device to operate reliably when driving capacitive loads. It is especially important in circuit configurations involving zone ECUs and their output stages (including individual ECUs) where large electrolytic capacitors are commonly used. If this capability is inefficient, inrush current cannot be adequately suppressed, leading to overheating that can result in malfunctions or reduced operational lifespan.
