3 Description

The UCC5714x is a single channel, highperformance,

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.
