Abstract
A power supply control device controls power supply through two branch paths branched from a common power supply path. Two N-channel FETs are respectively disposed in the two branch paths. A booster circuit outputs a voltage from a common output end, and applies a voltage to gates of the two FETs through a circuit resistor. Two charge resistors are respectively disposed in two applying paths through which a voltage is applied from the output end of the booster circuit to the gates of the two FETs. Each of two diodes are respectively connected between both ends of each of the two charge resistors. Cathodes of the two diodes are disposed on the side of the booster circuit.
