TPS7B87-Q1: Damaged TPS7B8750-Q1

Part Number: TPS7B87-Q1

Tool/software:

Hi Ti Forums,

I am using the TPS7B8750-Q1 to power a MAX14878AWA+ isolated CAN transceiver.  I have had 3 instances where the TPS7B8750-Q1 from what appears to be an over current condition resulting in thermal damage to the part.  I have tried to relocate this issue on the bench but I haven't been able to.  I have attached images below of the failed parts and the schematic for the parts in question.  I'm hoping to get some insights on how the TPS7B8750-Q1 is being damaged.

TIA,
