Claim Text:
1. A power supply control circuit, comprising: a power supply side terminal connected to a direct current power supply; a load side terminal connected to a load that is activated by power from the direct current power supply; a first FET (Field Effect Transistor) of a P type; a second FET of an N type; a first driving circuit for the first FET; a second driving circuit for the second FET; and a potential difference detection circuit, comprising: wherein the first FET and the second FET are connected in parallel with each other between the power supply side terminal and the load side terminal, and the potential difference detection circuit outputs a signal to the second driving circuit so as to turn on the second FET if the potential difference is equal to or higher than the given voltage value as a result of a comparison performed by the voltage comparison part.
