TPS25200: FAULT# pin forced 0V at VIN=0V or EN=0V

Part Number: TPS25200

Hi team,

 I want to confirm that the TPS25200 is not damaged under the following conditions.

Condition
  FAULT# pin is forced 0V by another devices.
 6pin IN : 0V or 3.3V or 5V
 4pin EN : 0V or 3.3V
  *Not required over current detection about these conditions.

 My understanding is TPS25200 does not damaged, because FAULT# is open drain. 

Regards,
Ogasawara

    Hi Ogasawara,

    Correct. FAULT# is open drain output, so, when FAULT# pin is forced with 0V by other source. There will not be any current through FAULT#. Hence TPS25200 device will not damage.

    Best Regards,
