<p>According to one embodiment, an electronic device includes a battery, a power supply circuit, and a charging circuit. The power supply circuit supplies power to components in the device by using DC power from an AC power supply or DC power from the battery. The charging circuit charges the battery by using the DC power from the AC power supply. The charging circuit includes a charger IC that controls a charging current and a charging voltage which are output from the charging circuit to the battery. The charger IC includes a first input terminal for monitoring a temperature of the AC power supply, and performs control for reducing the charging current when the temperature of the AC power supply exceeds a first temperature during the charging of the battery.</p> |
