The UCC5714x is a single channel, high-performance low-side gate driver capable of effectively driving MOSFET, IGBT, and SiC power switches. The UCC5714x has a typical peak drive strength of 3A.

The UCC5714x provides overcurrent protection with the OCP pin. When an overcurrent signal is detected on the OCP pin, the internal circuit pulls down the EN/FLT pin to report a fault and force OUT low. An external pullup circuit on the EN/FLT pin is required during normal operation of the driver. Pulling the EN/FLT pin low disables the driver. The EN/FLT also reports undervoltage lockout (UVLO) faults on VDD and overtemperature faults. The UCC5714x provides both 8V and 12V UVLO options for SiC and IGBT applications.
