UCC21750-Q1: Gate Driver not releasing pulses, DSAT FLT pin always Low

Part Number: UCC21750-Q1

We are referring to this circuit and bringing it to our gate driver while turning on the FLT pin is always low. and gate drivers are not releasing pulses.

RDY pin is high so that means all the supplies to the IC is proper.

We have tried resetting the fault using the RST/EN pin (making the pin low for some time and then bringing it high) but still the FTL pin is low and the IC is not releasing the pulses.

When we disabled the DESAT protection (by connecting the DESAT pin to COMM pin), then the IC is working fine, FLT pin is high and the output pulses are coming as desired.

Please help us with the DESAT protection issue.
