Abstract
There are provided a charge/discharge control circuit and a battery apparatus to which a load having a large capacitance is connected. In the battery apparatus, the charge/discharge control circuit includes an overdischarge latch circuit providing an overdischarge latch signal, based on a discharge control signal supplied thereto and a voltage of an external negative voltage input terminal, and a logic circuit supplied with an overdischarge detection signal and the overdischarge latch signal and providing the overdischarge detection signal to a control circuit while receiving the overdischarge latch signal, to thereby enable the power supply to the load to stop in a short processing time.
