Low-side Driver with Over-Current Protection and Fault/Enable

This IGBT driver module is a low-side gate driver that features integrated over-current protection. The primary functions of this module are its built-in over-current protection and enable/fault output capabilities. The board’s main components include the gate driver chip (1ED44176N01F), an SMD D2PK IGBT, and a current sense resistor. The chip is equipped with an over-current protection function, which has a typical threshold of 0.5V at the OCP (Over-Current Protection) point. When an over-current condition occurs, the driver output is automatically switched off. Simultaneously, the EN/FLT (Enable/Fault) pin is internally pulled down, and an internal current source charges the capacitor (C4) connected between the FLTC and VSS pins to program the fault clear time. This module is capable of driving loads up to 1A and can drive higher current with forced air cooling. It can operate within a load power supply range of 80-400V DC, making it a reliable and efficient solution for various applications.
