电池电量低指标是低成本、 高效率和环保

摘要：本应用指南介绍了使用低功耗CMOS比较器提供LED视觉显示电池电量低条件的电路。这个杠杆收购(低电量）被通过脉冲，指示灯的低频率和低工作周期。电路实现此不排放过量电池当前也会导致永久性的电池损坏，并最终危险废物处置。这种电路还有助于节省电池当前关闭周期中通过将比较器放置在关机。包含用于确定责任周期和比较器之旅点方程和电路分析。Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>AmplifierandComparatorCircuits>APP1872Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>Automotive>APP1872Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>BatteryManagement>APP1872Keywords:comparator,lowbattery,LED,lowcost,lowpowerconsumption,comparatorsFeb03,2003APPLICATIONNOTE1872Low-BatteryIndicatorIsLowCost,HighlyEfficient,andEnvironmentallyFriendlyFeb03,2003Abstract:Thisapplicationnotepresentsacircuitthatusesalow-powerCMOScomparatortoprovideanLEDvisualindicationofalow-batterycondition.ThisLBO(low
