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...
