GD3160: Advanced Single-Channel High-Voltage Isolated Automotive Gate Driver for SiC MOSFETs/IGBTs

Overview

PREPRODUCTION

The GD3160 is an improved, advanced single-channel high-voltage isolated gate driver with enhanced features for driving and protecting silicon carbide (SiC) MOSFETs and functional safety.

The GD3160’s SPI programmable drive, protection and fault reporting features allow users to optimize conditions for driving and protecting almost any SiC MOSFET or Si IGBT power switch.

ISO26262 compliant and automotive qualified, the GD3160 integrates BOM saving and functional safety features to support implementing ASIL D compliant and power density efficient xEV inverter solutions.
