Hi Team,

Please help me answer the follow question, thank you so much.

If the VIN of tps54227 fails due to static electricity or the like, is Vin either open or short for GND?

Hi,

Both might happen, the device has ESD protection circuits inside, it's not easily damaged and the damage needs to be sent to failure analyzed case by case. Thanks.
