【经验】如何从运输模式下激活锂电池充电管理芯片SGM41100？

时间： 2019-06-15 来源：世强

技术问答

圣邦微推出的锂电池充电管理芯片 SGM41100是一款专为小型锂离子电池或锂聚合物充电电池设计的IC。该装置具有所有常用于电池保护的电路，包括充电和放电开关、对过充电、过放电和过电流的检测和保护、对电池欠压预充电和深度放电的关机电路。SGM41100可工作于-40°C至+85°C温度范围，1.5X2X0.5mm小封装，方便小电池包的设计。

该产品的典型应用如下图：

需要注意的是，SGM41100为了避免在锂电池在运输和存储过程出现的意外短路和电池能量消耗，设置了运输保护模式。当初次安装上电池，或者电池拆卸后再次安装上后，SGM41100是处于锁定状态的，即IC内部的MOS是截止的，所以电池不会给后级电路正常供电。

为了解除这种保护，需要对SGM41100进行激活，目前官方给出的激活方式为以下三种：

1. 外加电源激活：在PCKP和PCKN之间加一个3~5V的充电电压，比如插入USB充电，大约1s即可。此后SGM41100将被激活，可以移除USB充电，由锂电池正常供电；

2. 短接法激活：在接上电池后，短接PCKN和BATN引脚1s左右，也可以激活SGM41100。可以通过按键或者复位开关或者低导通电阻MOS来实现这一操作。但是这里要注意，短接PCKN和BATN的时间内，相当于中止了SGM41100的保护功能。所以要确保激活按键不会被长时间按下，如果用其他电路激活也要确认好时序，不然将是SGM41100失效，带来其他的风险。

3. 接电容激活法：这个方法实质上和方法二很类似，通过在PCKN和BATN之间接一个电容来使上电时这两个引脚处于类似短路的状态。原厂推荐这个电容的容值是在220nf，但根据实际情况，可以适当扩大这个电容的容值以确保自启动的成功率。建议这里使用C0G或X7R等温度特性较为稳定的电容，以避免容值变动带来的启动失败。

以上为推荐的几种激活方式，如有其它问题，欢迎在平台上咨询。
