Part Number:TPS2113A
I'd like to know if I connect the positive terminal of a battery (Vbat+) to pin IN2 of TPS2113A, do I need to add polarity protection circuit (a grounded pFET) between Vbat+ and IN2 pin of TPS2113A or this is unnecessary, since IN2 is an input pin and there is no chance of reverse current flow back to the battery? Please advise if polarity protection is needed for Vbat+ to IN2 pin path. Thanks,
