3 Description

The UCC5880-Q1 device is an isolated, highly

configurable adjustable slew-rate gate driver targeted

to drive high power SiC MOSFETs and IGBTs in

EV/HEV applications. Power transistor protections

such as shunt resistor based over-current, overtemperature

(PTC, NTC, or diode), and DESAT

detection, including selectable soft turn-off or twolevel

soft turn-off during these faults. To further reduce

the application size, the UCC5880-Q1 integrates an

active Miller clamp, and an active gate pull-down

while the driver is unpowered. An integrated 10-bit

ADC enables monitoring of up to 2 analog inputs,

VCC2, DESAT, and the gate driver temperature

for enhanced system management. Diagnostics and

detection functions are integrated to simplify the

design of ASIL compliant systems. The parameters

and thresholds for these features are configurable

using the SPI, which allows the device to be used with

nearly any SiC MOSFET or IGBT.
