ROHM expands range of power devices to complete power solutions

At PCIM Europe 2019 (Power Conversion and Intelligent Motion) in Nuremberg, Germany (7–9 May), ROHM Semiconductor will showcase power semiconductor solutions focused on E-mobility and power supply applications.

The firm says that, with its new developments resulting from the group's extensive research and design initiatives, it is able to offer not only a full line-up of efficient, compact products for their applications but also a complete solution for the power tree.

Highlights in booth 312 (hall 9) include:

Automotive-grade SiC MOSFETs – In March, ROHM announced the addition of the SCT3xxxxxHR series to its range of automotive-grade silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs), yielding what is claimed to be the industry’s largest lineup of AEC-Q101-qualified SiC MOSFETs providing 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 existing product portfolio, offering new solutions to increase the flexibility and improve the design of industrial and automotive power systems. The line-up has a 3.75KV-isolation, AEC-Q100 gate driver device designed specifically 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) optimized to drive ROHM’s SiC MOSFET, improving the reliability of the system, says the firm.

1700V/250A full-SiC power module – ROHM claims that its 1700V/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 silicon solutions it allows the miniaturization of heat-sink and surrounded components in applications.

Power management ICs – Based on long-term experience with discrete power devices, ROHM also offers a broad lineup of system-on-chip (SoC) and application power management ICs for automotive, industrial and consumer market. The broad product portfolio also includes isolated DC–DC regulators as well as optimized AC–DC converters that allow the assembly of high-efficiency power supplies based on SiC technology.
