3 Description

The UCC5714x-Q1 is a single channel, highperformance,

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.
