Abstract
Provided is a charging and discharging protection circuit realizing low current consumption in an overcurrent detection state, easy calculation of an automatic return impedance, and high usability. A pull-down circuit for pulling down an overcurrent detection terminal to a VSS terminal is connected in series between the overcurrent detection terminal and a switching circuit. The switching circuit is connected in series between the pull-down circuit and the VSS terminal.
