3 Description

The UCC5710x-Q1 is a single channel, highperformance

low-side IGBT/SiC gate driver for

high power automotive application such as PTC

heaters, traction inverter active discharge circuit

and other auxiliary subsystems.It offers protection

features including Under-voltage-lock-out (UVLO),

Desaturation protection (DESAT), FAULT report ,

and Thermal shutdown protection. UCC5710x-Q1

has a typical peak drive strength of 3A. and it

can handle –5V on its inputs, which improves

robustness in systems with moderate ground

bouncing. The inputs are independent of supply

voltage and can be connected to most controller

outputs for maximum control flexibility. Depending

on the different pin configuration, the wide voltage

range of bias supply is provided in UCC5710xB-Q1

accommodates bipolar voltage. Also, the seperate

high and low driver outputs (UCC5710xC-Q1) and

enable funtion (UCC5710xW-Q1) are provided. An

accurate 5V output is available with UCC5710xB-Q1

and UCC5710xC-Q1.
