UCC256403: Avoiding tripping Fault

Part Number: UCC256403

Hi team,

My customer is using the UCC256403 in an LLC design and they need to be able to inhibit or stop the switching of the primary side LLC mosfets but need to do so without tripping the FAULT state which then results in a 1 second delay before restart once the inhibit signal is removed.

They are currently pulling down on the BLK pin but this of course trips the FALUT state and they get the undesired 1 second delay to restrart.

Is there any way to do avoid this undesired 1 second delay when inhibiting the device?

Thanks,

Connie
