The UCC5714x-Q1 is a single channel, high-performance, low-side gate driver capable of effectively driving MOSFET, IGBT, and SiC power switches. The UCC5714x-Q1 has a typical peak drive strength of 3A.
The UCC5714x-Q1 provides overcurrent protection with the OCP pin. When the overcurrent signal is detected on the OCP pin, the internal circuit pulls down the EN/FLT pin to report a fault and force OUT to low stage. 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 pin also reports the undervoltage lock out (UVLO) fault on VDD and the overtemperature fault. The UCC5714x-Q1 provides both 8V and 12V UVLO options for SiC and IGBT applications.
