6.1 Overview

The UCC5714x-Q1 device is a single-channel, high-speed, gate driver capable of effectively driving MOSFET, SiC, and IGBT power switches with 3A source and 3A sink (symmetrical drive) peak currents. The driver has a good transient handling capability on its output, as well as rail-to-rail drive capability and a small propagation delay, typically 26ns. The device has an overcurrent detection and fault reporting function to the low voltage side DSP/MCU. 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.

The input threshold of the UCC5714x-Q1 is compatible to TTL low-voltage logic, which is fixed and independent of VDD supply voltage. The driver can also work with CMOS based controllers as long as the threshold requirement is met. The 1V typical hysteresis offers noise immunity.

External pullup circuit on the EN/FLT pin is required during normal operation of the driver. Pulling EN/FLT low disables the driver. EN/FLT also reports the undervoltage lockout (UVLO) fault on VDD and the overtemperature fault.
