【应用】SGM41526锂电池充电管理芯片助力室外工业光能燃气表设计，充电效率95.2%，最大4A充电

时间： 2022-12-01 来源：世强

技术问答

光能款智能燃气表以吸收太阳能为能源，通过光伏电池吸收太阳能。再通过光伏板给锂电池充电，锂电池给计量采样供电使用。光能燃气表将用气数据、电量、信号、阀门状态、异常情况通过NB模组传输到管理平台。

光伏板收集太阳能，同时给锂电池充电，锂电池用来保证在无光照条件下燃气表可以正常使用。在这个过程中就需要一个锂电池充电管理芯片来保证锂电池安全、高效的充电。本文给大家推荐国产圣邦微推出的锂电池充电管理芯片SGM41526。具体的使用框图如下图所示：

1、芯片不需要MCU软件控制，通过外部电阻等配置充电电流等参数：快速充电的最大充电电流由ISET输入设置。电池电流由连接的电阻器RSR检测，最大4A充电，内部Buck PWM开关频率均为1.6MHz；

2、可支持单节、两节、三节不同需求的电池充电：电池单元的数量取决于CELL引脚的不同连接；

3、输入工作电压范围4.5V至22V，宽电压范围支持多种光伏板试用场景；

4、功耗（静态电流7.4μA）及充电效率95.2%，充电表现很好；

5、业级温度等级，封装尺寸均为QFN-5.5x3.5mm-24L。

SGM41526还同时具备一些保护功能：过温保护、输入欠压锁定、输入过电压保护等，在便携式设备、备用电池系统的表现良好，有需求可以在世强平台申请样品测试。
