TPS65381A-Q1: Using VCP as a reverse battery and shutoff gate supply

Ben holter
Intellectual 255 points
Part Number: TPS65381A-Q1
Other Parts Discussed in Thread: TPS1211-Q1, LM74502-Q1

I am looking to have back to back Nfets in order to allow physical shutoff of power from Vbat and to protect for reverse battery. Can i use VCP as the gate drive for this? Or is there a reference on how i could do this? looking to have low quiescent current, but i am using some devices which dont have standby modes so need to shut them off and your circuit only provides reverse battery protection examples.

    Hi Ben,

    Unfortunately, since this is an NDA part and your company does not have an NDA agreement with TI, I cannot really answer this question. However, from what you are describing perhaps a TPS1211-Q1 or LM74502-Q1 would be useful. Please get in contact with your local TI sales representative for further support.

    Best,
