Hi,
Was reading about bi-directional switches and came across this, may be of interest/relevant, maybe not.
Reverse Current Protection in Load Switches:
View attachment slva730.pdf
Page 2: "Reverse current is when there is a higher voltage at the output of a system than at the input, causing
current to flow backwards through the system. There are two common sources of reverse voltage: (1)
when power is disconnected from a system and (2) when the body diode of a FET becomes forwardbiased.
One source is when system input power is disconnected, a higher voltage can be left at the
output, which temporarily produces reverse current.
(...)
Reverse current can damage internal circuitry and power supplies. Depending on the path from output to
input, reverse current spikes can also damage cables and connectors."
