Abstract
A power supply control circuit includes a drive voltage generation circuit configured to generate a plurality of drive voltages by using a plurality of power supply voltages that are supplied from outside, a sequencer configured to stop, when supply of the plurality of power supply voltages is stopped in a predetermined order, generation of the plurality of drive voltages according to priority ranks set in advance, and a power supply monitor circuit configured to perform, when supply of one power supply voltage, among the plurality of power supply voltages, is stopped in an order different from the predetermined order but supply of other power supply voltages is continued, an operation for simultaneously stopping generation of drive voltages that are set at higher priority ranks than a priority rank for stopping generation of a drive voltage that uses the one power supply voltage.
