1. Description

The RAJ2930004AGM is a gate driver IC for IGBT and SiC MOSFET gate-drive in high voltage inverter

applications. Integrated 3750Vrms micro-isolators provide data transfer with high voltage isolation between

the primary circuit (MCU side) and the secondary circuit (IGBT side). In addition, it boasts superior CMTI

(Common Mode Transient Immunity) performance over 150 V/ns, providing reliable communication and

increased noise immunity while meeting the high voltages and fast switching speeds required in inverter

systems.

This device contains Gate drive circuit, Miller clamp circuit, and Soft turn-off circuit as well as several types

of protection circuits such as Overcurrent detection.
