METHOD OF CONTROLLING POWER SUPPLY AND ELECTRONIC DEVICE THEREOF

摘要

An electronic device includes: a power source unit including power supply circuitry configured to supply power and a signal corresponding to the power; a power management unit including power management circuitry configured to receive the power from the power source unit to supply the power to the electronic device; a controller configured to be activated when receiving the power from the power management unit to supply a signal corresponding to the power to the power management unit; and a plurality of submersion recognition patterns connected between the power source unit and the power management unit and between the power management unit and the controller, the plurality of submersion recognition patterns configured to recognize submersion of the electronic device, wherein the electronic device is shut down when at least one of the plurality of submersion recognition patterns recognizes submersion, and the electronic device is configured to maintain shutdown when submersion is recognized, even if a request for power supply occurs at the power source unit.
