Overview

The R2A25110KSP is a single channel IGBT gate-drive IC and suitable for high voltage inverter application. The Micro Isolator with the coreless transformer structure is adopted for data transfer with high voltage isolation between the primary circuit (MCU side) and the secondary circuit (IGBT side).

This device contains IGBT gate drive circuit, Miller clamp circuit, soft turn-off circuit as well as several types of protection circuits such as IGBT temperature detection. This device also supports driving parallel IGBTs.
