【选型】可pin-pin替换TI BQ25601的锂电池充电管理芯片SGM41511，具有更低功耗
在超声波水表应用中，有客户需要一款带I2C控制的3A单节锂电池充电芯片。之前客户选用的是TI的BQ25601，随着市场上国产化需求日益增多，客户急需找一款高性价比锂电充电芯片。圣邦微作为国内十大IC厂家，其下有多款锂电池充电管理芯片。根据客户的替换需求，笔者从电性能参数和封装pin脚等方面，重点介绍圣邦微的SGM41511可pin-pin替换TI BQ25601。以下为两者电性能参数对比：
通过以上电性能参数对比可知，
1、 圣邦微SGM41511与TI BQ25601有着相同的可编程充电电流范围0~3A，并且电池推荐充电电压都为4.208和4.352，另外，在OTG功能方面，两者的输出电压都为4.85~5.3V，最大电流也都是1.2A；
2、 与TI的BQ25601相比，圣邦微SGM41511有更宽的输入电压3.9~28V，更适合高压应用，9uA的静态电流，让SGM41511在低功耗性能表现更出色，在输出过压保护方面，两者都为可调节，SGM41511阈值电压可达21.5，提供更多设计选择；
3、 关于充电效率方面，两者表现不相上下，在5V_1A_3.8V条件下，TI的BQ25601表现更好，不过在5V_3A_3.8V条件下，圣邦微的SGM41511更胜一筹，除此以外，两者的工作温度都为-40~85℃，满足工业级应用，并且都有I2C控制。
圣邦微SGM41511与TI BQ25601有着相同封装QFN-4×4-24L，并且pin脚定义都相同，可实现pin-pin替换，下图为两者封装pin脚对比：
图2 SGM41511与BQ25601封装pin脚对比
圣邦微SGM41511与TI BQ25601典型应用电路基本一致，在实际应用设计时，可以直接替换。以下为两者典型应用电路：
