Title:
A charge-and-discharge control circuit, a charging and discharging control device, and a battery device
Document Type and Number:
Japanese Patent JP6143492
Kind Code:
B2
Abstract:
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 for detecting overcurrent of a secondary battery, the overcurrent detecting circuit being connected to the overcurrent detecting terminal, and a constant current circuit for causing a current to flow to the overcurrent detecting terminal.
