TPS92692-Q1: One-Fails–All-Fail Implement

Part Number: TPS92692-Q1

Dear Sir/Ms.

The customer designed 2 92692 ICs, and if any one is abnormal, the other one must be turned off !! (failure interlock)
 
But one of them will always have a PWM signal input. I wanted to use DIM PIN to interlock but there was no way.
Whether it can be achieved in the following way.


If the customer wants to implement One-Fails--All-Fail, any suggestions?

Best Regards,

Kami Huang
