TPS2553-1: FAULT pin isn't asserted although deglitch time is already passed

K.Yaita

Part Number: TPS2553-1

Hi Team,

My customer is evaluating TPS2553-1 in his system.

He set electrical load and increased load current gradually (15mA step), he found the state that shows output current is limited to the current limit value he set however FAULT pin wasn't asserted although deglitch time was already passed.
Is it possible case for TPS2553-1?

I believe it is possible case when output current is "just" identical with current limit value.
May I have your comments?

Best Regards,

Hi ,
Because of the current limit threshold have variation generlly is about +-6% , so customer can increase the current to exceed the max limit level to re-check again.
