TPS1H100-Q1: TPS1H100-Q1

Part Number: TPS1H100-Q1

I am connecting the TPS1H100 to a load that also has a large buffer cap of 470uF in parallel.

What can happen if the high voltage supply suddenly switches off and the buffercap is still charged so that a reverse current can flow through the body diode of the high side switch.

Will the device be able to detect reverse current since reverse polarity protection seems to work in a similar way.

Would I need to use an external diode in the output to block any reverse currents?
