Abstract
An example electronic device includes a power management circuit (PMIC), a plurality of voltage devices, and a time division sensing circuit. The PMIC includes a plurality of direct current (DC)-DC converters that generate a plurality of power supply voltages, respectively, based on a battery voltage. The voltage devices are distributed in the PMIC, and generate a plurality of temperature voltages that are inversely proportional to an ambient temperature. The time division sensing circuit converts the temperature voltages to sensed voltages, generates a decision signal indicating that at least one of the plurality of sensed voltages is equal to or smaller than a reference voltage based on a result of comparing each of the sensed voltages with the reference voltage by a time division scheme during a sensing period, and provides the decision signal to the PMIC. The PMIC performs a thermal shutdown on at least one of the DC-DC converters.
