Electronic device

Abstract

To detect deterioration of a capacitor at low cost.SOLUTION: An electronic device includes at least one processor. The processor outputs a first control signal for operating a transistor such that the transistor connected to a power source line repeats on / off, is connected to the power source line, acquires voltage between electrodes of a capacitor that is charged according to on of the transistor, determines whether charging of a capacitor is completed on the basis of the voltage between electrodes, and determines a deterioration state of the capacitor on the basis of the number of on times of the transistor until charging is completed after starting charging the capacitor.SELECTED DRAWING: Figure 1
