4.2 Kit featured components
4.2.1 Voltage domains, GD3160 pinout, logic header, and IGBT pinout
Low-voltage domain is an externally supplied 12 V DC (VPWR) primary supply for non-
isolated circuits, typically supplied by vehicle battery. The low-voltage domain includes
the interface between the MCU and GD3160 control registers and logic control.
Low-side driver and high-side driver domains are isolated high-voltage driver control
domains for SiC MOSFET or IGBT single phase connections and control circuits. Pins
on bottom of board are designed to easily connect to a compatible three-phase SiC
MOSFET or IGBT module.

4.2.2 GD3160 pinout and MCU interface pinout
See GD3160 advanced IGBT/SiC gate driver data sheet for specific information about
pinout, pin descriptions, specifications, and operating modes. VSUP/VPWR DC supply
terminal is a low voltage input connection for supplying power to the low voltage non-
isolated die and related circuitry. Typically supplied by vehicle b12 V DC.
MCU connector is a 2×32-pin PCIe interface connector for use with either MPC5775B/
E-EVB or MPC5744P or MPC5777C 32-bit MCU board or any other MCU of preference.
An MCU is needed for SPI communication and control of advanced IGBT/SiC gate drive
devices (GD3160).
KITGD3160TREVB included with the kit can be attached to this board at bottom of dual
row header pin interface. All gate drivers can be accessed via SPI control using FlexGUI
software.
Note:
Double pulse and short-circuit tests can be conducted on Phase U only. See
