Advanced single-channel gate driver for Insulated Gate Bipolar Transistors (IGBTs)

The MC33GD3100 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 stress during faults. Accurate and

configurable under voltage lockout (UVLO) provides protection while ensuring sufficient

gate drive voltage headroom.

The MC33GD3100 autonomously manages severe faults and reports faults and status

via INTB pin 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). It meets the stringent requirements of automotive

applications and is fully AEC-Q100 grade 1 qualified.
