General description

The GD3160 is an advanced, single-channel gate driver for IGBTs and SiC power devices. Integrated Galvanic

isolation and low on-resistance drive transistors provide high charging and discharging current, low dynamic

saturation voltage and rail-to-rail gate voltage control.

Current and temperature sense minimizes IGBT/SiC stress during faults. Accurate and configurable

undervoltage lockout (UVLO) provides protection while ensuring sufficient gate-drive voltage headroom.

The GD3160 autonomously manages severe faults and reports faults and status via INTB and/or INTA pins

and an SPI interface. It is capable of directly driving gates of most IGBTs and SiC MOSFETs. Self test, control,

and protection functions are included for design of high-reliability systems (ASIL C/D). The GD3160 meets the

stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified.
