Range of power devices expanded to offer complete solutions
At PCIM in Nuremberg, Germany (7th-9th May, 2019), ROHM Semiconductor will showcase power semiconductor solutions focused on E-mobility and power supply applications. Energy savings and reduced system costs in all kinds of systems are heavily influenced by choosing the right power device.
With its new developments resulting from the group's extensive research and design initiatives, ROHM is able to offer customers not only a full line-up of efficient, compact products for their applications, but also a complete solution for the power tree.
Highlights at ROHM’s booth in hall 9, both 312:
Automotive grade SiC MOSFETs ROHM recently announced the extension of new automotive-grade SiC MOSFETs in its line-up, namely SCT3xxxxxHR series. This series has allowed the company to achieve the industry's largest lineup of AEC-Q101 qualified SiC MOSFETs that provide the high reliability necessary for automotive on-board chargers and DC/DC converters.
Gate driver for SiC MOSFETs
The new series of Isolated Gate Driver ICs for power MOSFETs will expand ROHM’s current product portfolio, offering new solutions to increase the flexibility and improves the design of industrial and automotive power systems.
The line-up has a 3,75KV isolation, AEC-Q100 gate driver device specifically designed to drive SiC power MOSFETs. It has a built-in active miller clamping to prevent parasitic turn on effects and integrates an Under-Voltage Lock-Out (UVLO) optimised to drive ROHM's SiC MOSFET. These functions improve the reliability of the system.
1,700V/250A Full SiC Power Module
ROHM 1,700V/250A Full SiC Power Module has the industry’s highest level of reliability in high temperature and high humidity standards. With better switching characteristics than Si solutions it allows the miniaturisation of heatsink and surrounded components in applications.
New Presto MOS Line-up
The new JN series of 600V super-junction MOSFET with Fast Recovery Diode (FRD) implemented in its body diode has been released. JN series is an optimised MOSFET for inverter/converter applications, soft recovery characteristics of FRD and optimised parasitic capacitances contribute to reduce noise and prevent self-turn-on issue in bridge topology. ROHM offers JN series with variety of packages and wide RDS(on) variants.
ROHM's RGS series is automotive graded switching IGBT with high robustness against short circuit failure. RGS series acquires two types of collector-emitter Voltage - 650V guaranteed 8µs short circuit withstand and 1,200V with 10µs short circuit withstand time. They can be selected according to battery voltage of electric vehicles. RGS series is suitable to automotive e-compressor and PTC heater application.
Power Management ICs Based on long term experience with discrete power devices, ROHM Semiconductor also offers a broad lineup of SoC and application power management ICs for automotive, industrial and consumer market. The broad product portfolio also includes isolated DCDC regulators as well as optimised ACDC converters which allow to build-up high efficient power supplies based on SiC technology.
In addition, ROHM continues to expand the technical boundaries with new concepts like Quick Buck-Boost converters or ROHM’s new Nano Pulse ControlTM technology.
