TPS2552: Failure Mode leading to IN-OUT Open/Short

Shinichi Yokota

Part Number: TPS2552

Hello,

Does TPS2552 have a failure mode that can lead to pin open or short-circuit between IN and OUT?

If yes, which can occur? Open or short-circuit.

If both can happen, what's the percentage of these?

Best regards,

Hi Shinichi-san,

It's random. Both are possible. Don't have the statistic percentage of these.

If you have any other concern, contact me any time.

If you think resolved, please help click 'Issue is solved button'.

Thanks.

Ziv-san,

When a short-circuit failure happens, can the TPS2552 emit smoke, set fire, or burn?

I guess the package mold material is fire-resistant.

Best regards,

Hi Yokota-san,

1. The part is with short to ground protection. It can't damage the IC.

2. The voltage above ABS can damage the IC. As I test on bench, doesn't emit smoke, fire or burn.

If you have any other concern, contact me any time.
