Abstract:
An electronic device according to an embodiment may include: a plurality of loads, a processor, and a power management circuit configured to provide the plurality of loads with a power, wherein the power management circuit may include a plurality of regulators configured to adjust a voltage of a power received from a power source and output a voltage-adjusted power, a switching circuit configured to connect at least one of the plurality of regulators to at least one of the plurality of loads, a plurality of power sensors each power sensor being configured to measure a magnitude of a power input to each of the plurality of loads, and a controller. The controller may be configured to obtain information related to an operation of each of the plurality of loads from the processor, obtain the magnitude of the power input to each of the plurality of loads from each of the plurality of power sensors, and identify a load which operates abnormally among the plurality of loads based on the magnitude of the power input to each of the plurality of loads and the information related to the operation of each of the plurality of loads.
