Abstract
A power supply control circuit includes a power storage that stores power generated by energy harvesting, a function circuit that operates a specific function, a first switch allocated between the power storage and the function circuit and supplies or not supplies the power to the function circuit, a supply controller that monitors a voltage corresponding to the power stored in the power storage, and when the voltage of the power storage is equal to or above a first voltage, controls the first switch so that the function circuit is supplied with the power stored in the power storage, and a power consumption controller that controls, based on the voltage of the power storage, power to be consumed by the function circuit, the power being supplied from the power storage to the function circuit by switching of the first switch.
