Advanced High Voltage Isolated Gate Driver for IGBT and SiC MOSFETs

GD3100

Roll over image to zoom in

The GD3100 is an advanced single-channel gate driver for IGBTs/SiC. 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 under voltage lockout provides protection while ensuring sufficient gate drive voltage headroom
  • Autonomously manages severe faults and reports faults and status via INTB pin and an SPI interface. It is capable of directly driving gates of many IGBTs/SiC
  • Self-test, control and protection functions are included for the design of high-reliability systems
