铅酸蓄电池的过流/过放电保护

资料介绍
摘要:本应用笔记介绍了与内部的双比较器的电流检测放大器的使用,以监测和防止过低的电池电压和电池电流过高。虽然书面铅酸蓄电池,电路和概念可以扩展到镍镉电池,锂离子和其他化学电池。外部电源的P沟道MOSFET系列电池和负载。作为一个常闭开关可打开它的工作原理,如果电流检测放大器和比较器检测高负荷电流或电池电压低。目前比较高,可以锁定检测简短的过电流和外部按钮复位。

APPLICATION NOTE 2015
Overcurrent/Overdischarge Protection for Lead-Acid Batteries

Abstract: This application note describes the use of a current-sense amplifier with internal dual comparators to
monitor and protect against too low battery voltage and too high battery current. While written for lead-acid
batteries, the circuit and concept can be extended to NiCd, Li-ion and other battery chemistries. An external
power P-channel MOSFET is in series with the battery and its load. It works as a normally closed switch which
can be opened if the current-sense amplifier and……
