Advanced IGBT/SiC gate driver
Rev. 9.0 — 5 March 2020
Product short data sheet
1 General description
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.
