The TIDA-00794 reference design from Texas Instruments is a temp sensing solution for IGBT thermal protection in HEV/EV traction inverter system. It monitors the IGBT temperature via the NTC thermistor integrated inside the IGBT module. It provides thermal shut down to the IGBT gate drivers once the NTC thermistor temperature rises above the programmed threshold.
The design includes the IGBT isolated gate drivers, isolation to the high voltage, NTC signal conditioning, Load resistor, and I2C interface to the MSP430, which enables the design system to run independently under high power ratings.
