UCC27531: The device broke even if the VDD is below 32V

Part Number: UCC27531

Hi Team,

In the customer's board containing UCC27531, the device VDD has an overshoot upon power up, and it rise at 30V (but it never exceeded 30V). The problem is it breaks the UCC27531 every time it happens. The customer has solved the issue by slowing down the rise of VDD and eliminating the overshoot. The customer wants to understand why did it broke if the VDD is below 32V (32V is the maximum supply voltage of VDD based on Section 7.3 of the datasheet).

Regards,

Danilo
