3 Introduction
This document is the user guide for the RDGD3162I3PH5EVB reference design.
This document is intended for the engineers involved in the evaluation, design,
implementation, and validation of the GD3162 single-channel gate driver for insulated
gate bipolar transistor (IGBT)/SiC.
The scope of this document is to provide the user with information to evaluate the
GD3162 single channel gate driver for IGBT/SiC. This document covers connecting the
hardware, installing the software and tools, configuring the environment and using the kit.
The RDGD3162I3PH5EVB is a fully functional three-phase inverter evaluation board
populated with six GD3162 gate drivers with fault management and supporting circuitry.
This board supports serial peripheral interface (SPI) daisy chain communication for
programming and communication with three high-side gate drivers and three low-side
gate drivers independently, or all six gate drivers at the same time.
This board has low-voltage isolation and high-voltage isolation with gate drive integrated
galvanic signal isolation. Other supporting features on the board include desaturation
short-circuit detection, IGBT/SiC temperature sensing, onboard isolated flyback supplies,
DC link bus voltage monitoring, phase current sensing, DC link bus current sense, and
motor resolver excitation/processing. See GD3162 data sheet for additional gate drive
features.
