Hi TI team, I have a small query regarding any possible failure mode of UCC256603 when the external Aux supply is not available but High voltage is applied at HS (split capacitor half voltage) and sense voltage at BLK pin.

Hi Ashok,
Having voltage at the HS pin shouldn't be a problem when VCC is not suppled.
