Title:
POWER SUPPLY CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/006575
Kind Code:
A1
Abstract:
This power supply control circuit is installed in a predetermined device having a plurality of electronic components driven by at least one of a plurality of drive voltages and comprises: a drive voltage generation circuit for generating a plurality of drive voltages using a plurality of power supply voltages supplied from the outside of the predetermined device; a sequencer that stops generation of the plurality of drive voltages on the basis of a preset priority order when supply of the plurality of power supply voltages is stopped in a predetermined order; and a power source monitoring circuit that operates so that when supply of one power supply voltage among the plurality of power supply voltages is stopped in an order different from the predetermined order while supply of the other power supply voltages is continued, the generation of drive voltages set at a higher priority than the priority of the generation of a drive voltage using the one power supply voltage which was stopped, are simultaneously stopped.
