4 Getting to know the hardware
4.1 Overview
The FRDMGD31RPEVM is a half-bridge evaluation kit populated with two GD3100
single channel gate drive devices. The kit includes the Freedom KL25Z microcontroller
hardware for interfacing a PC installed with FlexGUI software for communication to the
serial peripheral interface (SPI) registers on the GD3100 gate drive devices in either
daisy chain or standalone configuration.
The KITGD3160TREVB translator board is used to translate 3.3 V signals to 5.0 V
signals between the MCU and GD3100 gate drivers. The evaluation kit can be connected
to a compatible insulated gate bipolar transistor (IGBT) or SiC module for half-bridge
evaluations and applications development.
4.2 Board features
•
Capability to connect to RoadPak SiC module for half-bridge evaluations
•
Negative VEE gate low drive level (−3.9 V DC)
•
VCCREG regulated high gate drive level (+15 V DC)
•
Jumper configurable for disabling dead time fault protection when short-circuit testing
•
Easy access power, ground, and signal test points
•
Easy to install and use FlexGUI for interfacing via SPI through PC; software includes
double pulse and short-circuit testing capability
•
DC link bus voltage monitor on low-side driver via AMUXIN and AOUT
•
Negative temperature coefficient (NTC) connection and configurable for monitoring
module temperature
