随着人们对语言学习和翻译的需求增加，电子词典成为了一种必备的工具。其续航能力成为人们选择此类产品时要重点考虑的因素之一。因此，在工程师们在开始设计此类产品之初，就需要选用合适的部件，制定高效电子词典充电方案，来提升电池的续航能力。

工程师们可以选用线性锂电池充电芯片，实现对电子词典电池的快速充电，而减少电池等待充电的时间，提高电池的使用效率和续航。线性锂电池充电芯片通过对电池电量、充电电流和电池温度等参数的检测和控制，实现了对锂电池的高效、安全充电。

针对电子词典方案中用到的线性锂电池充电芯片选择，笔者推荐虹茂的一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器 HM5056R，该产品带电池正负极反接保护且温度自适应可实现充电速率最大化。其采用ESOP8封装形式且带有散热片使得成为电子词典的理想选择。

图 1 典型电路

虹茂HM5056R线性锂电池充电芯片可以被应用于电子词典的锂电池充电管理系统中，采用了内部PMOSFET 架构，加防倒充电路，不需要外部隔离二极管。为了保证电子词典充电的安全性和稳定性，该芯片采用了热限制技术，可对电子词典电池充电时的温度进行监测和控制。如果芯片温度升至约140℃的预设值以上，则一个内部热反馈环路将减小设定的充电电流，直到155℃以上减小电流至0。

为让锂电池避免电池过度放电，延长电池寿命，虹茂对线性锂电池充电芯片加入了欠压闭锁功能。其V_CC欠压闭锁门限为3.6V，当电池电压降至3.6V以下时，芯片会自动断开充电电路。有效的防止电池电压过低时继续充电，从而保护电子词典电池不受过度充电的损害。

同时，HM5056R充电电流软启动功能提高了电子词典的充电效率和充电安全性。当一个充电循环被启动时，充电电流将在20μS左右的时间里从0上升至满幅全标度值。在启动过程中，这能够起到最大限度地减小电源上的瞬变电流负载的作用。
