6.1 Overview

The UCC5710x-Q1 device is a single-channel, high-speed, gate driver capable of effectively driving MOSFET, SiC MOSFET, and IGBT power switches with 3-A source and 3-A sink (symmetrical drive) peak current. The driver has a good transient handling capability on its output due to reverse currents, as well as rail-to-rail drive capability and small propagation delay, typically 26ns. The device has the state-of-art DESAT detection time and fault reporting function to the low voltage side DSP/MCU. Soft turn off is triggered when the DESAT fault is detected, minimizing the short circuit energy while reducing the overshoot voltage on the switch.

The input threshold of the UCC5710x-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 1-V typical hysteresis offers excellent noise immunity.

In the UCC5710xW-Q1, the driver has an EN pin with fixed TTL compatible threshold. EN is internally pulled up. Pulling EN low disables the driver, while leaving EN open provides normal operation. The UCC5710xB-Q1 and UCC5710xC-Q1 offer an additional 5V output (VREF) that source up to 20mA function.
