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 the over current protection with the OCP pin. When the over current signal is detected on the OCP pin, the internal circuit will pull down the EN/FLT pin to report fault and force the OUT to low stage. An external pullup circuit on the EN/FLT is required during the normal operation of the driver. Pulling the EN/FLT low will disable the driver. The EN/FLT would also report the under voltage lock out (UVLO) fault on VDD and the over temperature fault. The UCC5714x provide both 8V and 12V UVLO options for SiC and IGBT applications.
