A power supply control apparatus for controlling a power supply circuit for outputting voltages of at least two systems is constructed by a first power supply circuit for generating a first voltage and a second power supply circuit for generating a second voltage, a controller circuit which is driven by the first voltage, a disconnecting circuit for disconnecting the second voltage by the controller circuit in accordance with a predetermined condition, a power supply controller circuit for controlling the second power supply circuit on the basis of the second voltage, and a supplying circuit for supplying a signal indicative of a state in which the second voltage has been outputted to the power supply controller circuit when the second voltage is disconnected by the disconnecting circuit.
