Mobile information processing device, integrated circuit, and battery pack

A mobile information processing device comprising:

• a power generator configured to generate electric power;
• a secondary battery configured to store electric power;
• a power feeding circuit configured to supply electric power generated by the power generator to the secondary battery;
• an electronic circuit to which electric power is supplied from the secondary battery;
• an over-discharge detection circuit that is supplied with electric power from the secondary battery, and is configured to detect whether or not the secondary battery is in an over-discharged state, and upon detecting that the secondary battery is in an over-discharged state over a predetermined period, stop a detection operation according to an enable signal;
• and
• a power down cancel circuit configured to, when the over-discharge detection circuit has stopped the detection operation, cause the over-discharge detection circuit to re-start the detection operation when a current supplied to a detection terminal from the power feeding circuit is more than a predetermined current.
