This circuit takes input power connections and outputs them but with reverse polarity and reverse current protection by using both a load switch circuit followed by an ideal diode circuit.
It also takes an "activation signal" which is 3.3v to enable the load switch, power will be disconnected without it.
If load switching is not required but just a continuously on circuit with protection then you can tie "Activation" to input voltage positive terminal.
It can be modified to suit any situation, which is the duty of the user.
