Battery state monitoring circuit and battery device |
摘要 |
Provided are a battery state monitoring circuit and a battery device that are capable of reliably controlling charge by a charger even if a voltage of a secondary battery drops to around 0 V. In the battery device provided with the battery state monitoring circuit, respective gate voltages of a P-type metal oxide semiconductor (PMOS) transistor and an N-type metal oxide semiconductor (NMOS) transistor, which together form a voltage detection circuit for detecting a voltage of around 0 V of the secondary battery, are applied by a voltage dividing resistor circuit that is connected across terminals of the secondary battery.
