EiceDRIVER™ SiC MOSFET Gate Driver ICs

Overview

Gate-Driver ICs with perfect fit to CoolSiC™ MOSFET

Ultra-fast switching 650 V and 1200 V power transistors such as CoolSiC™ MOSFETs typically are best driven by gate-driver ICs with integrated galvanic isolation.

These gate drivers incorporate the most important key features and parameters typically recommended for silicon-carbide MOSFETs driving such as tight propagation delay matching, precise input filters, wide output-side supply range, negative gate voltage capability, extended CMTI capability, active Miller clamp, DESAT protection, UVLO, and last but not least input-to-output galvanic isolation.

In SiC MOSFET half-bridges, where the 3.3 mm channel-to-channel creepage distance between the two output channels of a dual-channel isolated gate-driver IC is insufficient, a hybrid combination consisting of one single-channel isolated gate-driver IC for the boot-strapped high-side, and one non-isolated gate-driver IC with truly differential inputs can be a compelling choice. This combination permits optimization of the gate-loop layout and offers separate low-impedance source and sink outputs.
