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。Maxim>AppNotes>BATTERYMANAGEMENTPOWER-SUPPLYCIRCUITSKeywords:batteryprotection,overcurrent,undervoltage,currentsenseamplifier,leadacidbattery,overMay11,2003discharge,currentsenseampAPPLICATIONNOTE2015Overcurrent/OverdischargeProtectionforLead-AcidBatteriesAbstract:Thisapplicationnotedescribestheuseofacurrent-senseamplifierwithinternaldualcomparatorstomonitorandprotectagainsttoolowbatteryvoltageandtoohighbatterycurrent.Whilewrittenforlead-acidbatteries,thecircuitandconceptcanbeextendedtoNiCd,Li-ionandotherbatterychemistries.AnexternalpowerP-channelMOSFETisinserieswiththebatteryanditsload.Itworksasanormallyclosedswitchwhichcanbeopenedifthecurrent-senseamplifierand……
