断开负荷开关停止电池放电保护可充电电池

资料介绍
摘要: 这个设计理念显示电压检测器、 MAX8211 和电荷泵逆变器、 MAX680,窗体 load-disconnect 开关切换。此 load-detect 开关使用仅 8µA,并将暂停从深放电保护可充电电池的电池放电。

APPLICATION NOTE 968
Load-Disconnect Switch Halts Battery Discharge to Protect
Rechargeable Batteries


Abstract:This design idea shows a voltage detector, the MAX8211, and charge pump inverter, the MAX680, that form a load-
disconnect switch. This load-detect switch uses only 8A and halts battery discharge to protect rechargeable batteries from deep
discharge.

Deep discharge can damage a rechargeable battery. The Figure 1 circuit, by disconnecting the battery from its load, halts battery
discharge at a predetermined level of declining terminal voltage. Transistor Q1 acts as the switch. ……
