BATTERY STATE MONITORING CIRCUIT AND BATTERY DEVICE |
摘要 |
Provided is a battery state monitoring circuit which detects that a voltage of a secondary battery has decreased abruptly because of an overcurrent, thereby being capable of protecting a battery device from an abrupt decrease in voltage of the secondary battery caused by the overcurrent. The battery state monitoring circuit includes a voltage comparator circuit and a power supply voltage detection circuit for detecting an abrupt decrease in power supply voltage, in which the voltage comparator circuit detects a normal overcurrent while the power supply voltage detection circuit detects the abrupt decrease in power supply voltage caused by load short-circuit. |
