CHARGE AND DISCHARGE CONTROL CIRCUIT, CHARGE AND DISCHARGE CONTROL UNIT, AND BATTERY DEVICE

摘要

Provided is a highly safe battery device in which the accuracy of an overcurrent detection current value is high. A charge and discharge control circuit includes an overcurrent detecting terminal, an overcurrent detecting circuit which detects overcurrent of a secondary battery and is connected to the overcurrent detecting terminal, and a constant current circuit for enabling a current to flow to the overcurrent detecting terminal.
