Abstract
Provided is a battery state monitoring circuit including: a charge/discharge control circuit for detecting and controlling a state of a secondary battery; an automatic recovery circuit; a temperature sensor circuit; and a comparator for comparing a voltage of an output terminal of the automatic recovery circuit and a voltage of the secondary battery, and outputting a signal indicative of a result of the comparison to the temperature sensor circuit, to control an operation of the temperature sensor circuit. The temperature sensor circuit operates only when the output of the automatic recovery circuit is larger, that is, only when a charger is connected between external terminals.
