3 Description

The UCC5710x is a single channel, high-performance

low-side IGBT/SiC gate driver for high power

automotive applications 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. The UCC5710x 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 the bias

supply provided in the UCC5710xB accommodates

bipolar voltage. Also, seperate high and low driver

outputs (UCC5710xC) and an enable function

(UCC5710xW) are provided. An accurate 5V output

is available with the UCC5710xB and UCC5710xC.
