Abstract
A power control circuit includes: a differential voltage monitor configured to monitor a differential voltage between a first voltage and a second voltage, and control a switching element to be turned on and off, wherein the differential voltage monitor controls the switching element in such a manner that in a case where the differential voltage is increased, when the differential voltage is lower than a first reference voltage, the switching element is turned off, and when the differential voltage is equal to or higher than the first reference voltage, the switching element is turned on, and in a case where the differential voltage is decreased, when the differential voltage is higher than a second reference voltage, the switching element is turned on, and when the differential voltage is equal to or lower than the second reference voltage, the switching element is turned off.
