Power supply management integrated circuit, electronic device, and control method of power supply management integrated circuit

摘要

A communication amount and a processing load of an external circuit of a power supply management integrated circuit are reduced.;The power supply management integrated circuit includes a state determination unit and a battery remaining quantity measurement unit. In the power supply management integrated circuit, the state determination unit determines which one of a plurality of states corresponding to different cycles a charge/discharge state of a battery falls under. Furthermore, in the power supply management integrated circuit, the battery remaining quantity measurement unit measures a battery remaining quantity of the battery each time when the cycle according to the state of charge/discharge state of the battery determined by the state determination unit elapses.
