3-Phase Reference Design for HybridPACK™ Drive IGBT/SiC Module Featuring GD3100

RDGD3100I3PH5EVB

Roll over image to zoom in

The RDGD3100I3PH5EVB is a fully functional three-phase power gate drive reference design populated with six GD3100 gate drivers with fault management and supporting control circuitry.

This board supports SPI daisy chain communication for programming and communication with three high-side gate drivers and three low-side gate drivers independently. Included is S32SDEV-CON18 PCIe cable for connecting to MCU controller board MPC5777C-DEVB (not included). This board is designed to be connected to a HybridPACK™ Drive IGBT module footprint (not included).
