UCC5870QDWJEVM-026 Evaluation Module User's Guide
The evaluation module is designed for evaluation of TI's functional safety compliant 15-A isolated single-
channel gate driver UCC5870-Q1 with advanced protection functions. This EVM is targeted to drive high
power SiC MOSFETs or Si IGBTs in EV/HEV applications. Protection functions such as DESAT short
circuit protection, shunt current sensing support, soft turn-off, VCE overvoltage clamping, UVLO and
OVLO of gate driver power supplies, temperature monitoring and thermal shutdown, and gate monitoring
are included to support system's demanding high reliability. This driver also incorporates sophisticated
diagnostic, protection, and monitoring features through a serial peripheral interface (SPI).
The UCC5870-Q1 evaluation module also includes a MCU daughter board to support SPI communication
and program the UCC5870-Q1, a dedicated GUI is developed for configuring and evaluating UCC5870-
Q1. This evaluation module has pin outputs that support the 820A 750V IGBT module FS820R08A6P2B
connection for high power double pulses test and short circuit test.
