Abstract
Provided is a charge/discharge control circuit for controlling charging and discharging of a secondary cell. The charge/discharge control circuit includes a positive power supply terminal and a negative power supply terminal configured to monitor a voltage of the secondary cell, a charge control signal output terminal from which a charge control signal is output, the charge control signal controlling stopping and allowing charging of the secondary cell, a discharge control signal output terminal, an overcurrent detection terminal, an overcurrent cancel terminal, an external voltage input terminal provided separately from the overcurrent cancel terminal, a discharge overcurrent detection circuit connected to the overcurrent detection terminal, to which a discharge overcurrent detection voltage is set, and a discharge overcurrent cancel circuit connected to the overcurrent cancel terminal, to which a discharge overcurrent cancel voltage is set.
