The MC33GD3100 is an advanced single channel ga     te   driver for IGBTs. Integrated Galvanic isola     ti   on and low on-resistance drive transisto     rs   provide high charging and discharging current， low dyna     mi   c satura  TI on voltage and r     ai   l-to-rail gate voltage control. Current and temperature sense minimizes IGBT stress during faults. Accurate and configurable under voltage lockout （     UV   LO） provides protec  TI on while ensuring sufficient gate drive voltage headroom.

The MC33GD3100 autonomously manages severe faults and reports faults and status     via   INTB pin and an SPI inte     rf   ace. It is capable of directly driving gates of most IGBTs. Self test， control and protec  TI on func  TI ons 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 qual     if   ied.

半桥评估板FRDM-GD3100EVM

The FRDM-GD3100EVM is a half-bridge evaluation kit populated with two MC33GD3100 single channel IGBT gate drive devices on a half-bridge evaluation board. The kit includes the Freedom KL25Z microcontroller hardware for interfacing a PC instal     led   with SPIGen software for communication to the SPI registers on the MC33GD3100 gate drive devices in either daisy chain or standalone configuration.

The GD3100 translator board is used to translate 3.3 V signals to 5.0 V signals between the     MCU   and MC33GD3100 gate drivers. The evaluation kit     can   be connected to a single phase of a Fuji M653 or M6+ IGBT module for half-bridge evaluations and applications development.
