摘要： In a charge and discharge control circuit, a mode control part manages a normal mode in which voltages at a power terminal and an overcurrent detection terminal are monitored, a time-shortening mode in which predetermined delay times for detecting an overcharge, an overdischarge, and an overcurrent are shortened, and a protection mode in which a signal to stop a charge current or a discharge current is output when an abnormality is detected in the normal mode. A transition is made from the normal mode to the time-shortening mode when the voltage at the power terminal exceeds a predetermined value, and a transition is made from the time-shortening mode to the protection mode when one of the overcharge, overdischarge, and overcurrent is detected.
