创瑞科技(AIT)推出的单节锂电池保护电路 A4001使单电池锂离子聚合物电池供电系统（如手机）不会因过充、过放电和/或过电流而损坏或降低寿命。超小型封装和最少的外部组件使其成为理想的低成本锂电池保护电路方案。非常低的待机电流和50mV过充检测电压精度可以满足消费类产品的要求。

锂电池具有放电电流大、内阻低、寿命长、无记忆效应等优点，但锂电池在使用中严禁过充电、过放电和短路，否则将会引起电池寿命缩短或起火、爆炸等事故，所以锂电池的充放电过程必须有可靠的保护措施。

单节锂电池的最高充电终止电压为4.2V，不能过充，否则会因正极的锂离子丢失太多而使电池报废。对锂电池充电时先恒流充电至锂电池两端电压为4.2V后，转入恒压充电模式；当恒压充电电流降至设置值（根据电池额定容量）时，应停止充电。

充电电流（mA）可为0.1～1.5倍电池容量，例如：1800mAh的锂电池，其充电电流可控制在180mA～2700mA之间。常规充电电流可选择在0.5倍电池容量左右，充电时间约为2～3小时。

锂电池放电时必须保留一部分锂离子在负极，以保证在下次充电时锂离子能够畅通地嵌入通道。否则，电池寿命会缩短。这就要严格限制放电终止最低电压，也就是说锂电池不能过放电。单节锂电池的放电终止电压没有一定规则，对于消费类产品的锂电池最低设置在2.5V左右，不能太低，实际上放电电压太低，负载电路也难以正常工作。电池放电时间长短与电池容量、放电电流大小有关。电池放电时间（小时）＝电池容量／放电电流，且锂电池放电电流（mA）不应超过电池容量的3倍，否则会使电池损坏。

图1. A4001锂电池充放电保护电路

如图1所示，这是业界最简单的锂电池保护电路，A4001通过对VDD电压的检测，可以检测电池的过充电和过放电状态，当检测电压超过4.3V时（通常手机电池额定电压为4.2V），OC控制充电MOSFET断开，终止充电。二极管可以保持放电回路开通，当电压降到4.1V时，OC控制充电MOSFET导通，可继续充电；在外部没有充电情况下，手机长时间使用，锂电池过放电时，可检测VDD电压低到2.4V时，OD控制放电MOSFET断开，停止放电。并联的二极管可以保持充电回路开通，当外部充电使检测到电池电压达到3V时，OD控制放电MOSFET重新导通。

R2上的电压可用来检测过电流状态和电池短路，当电压大于150mv(典型值)被认为是过电流，内部逻辑电路可控制两个MOSFET。当该电压达1.3V左右时，被认为电池短路，保护电路将及时断开通路。

由于A4001的微型化，3uA的超低静态电流；0.1uA的POWER-DOWN电流；A4001的过充保护电压误差为50mV；内部电路产生延迟时间，无需外部电容器；SOT-26封装。应用电路非常简单，因为电路检测的阈值是固定的，并适合手机锂电池应用，所以不需要另行设置。因专为通用锂电池包设计，内部电路相对比较简单，所以A4001是一个实用的低成本的手机锂电池保护方案。
