德州仪器(TI)bq27426电池电量监测计是一款单节电池电量监测计,只需进行少量用户配置和系统微控制器固件开发工作即可快速实现系统调通。
该器件提供三种预编程的化学配置文件,可最大限度减少用户配置并帮助客户管理项目中不同电池化学成分库存.bq27426电池电量监测计在休眠模式下具有超低功耗,有助于延长电池的运行时间。可配置中断有助于节省系统功耗,释放主机使其停止继续轮询。外部热敏电阻为精确温度感测量进行电量监测,可提供诸如剩余电量(mAh),充电状态(%)和电池信息。
通过bq27426电量监测计进行电池电量监测时,只需将PACK +(P +)与PACK-(P-)连接至可拆卸电池组或嵌入式电池电路即可。采用微9球,1.62毫米×1.58毫米,0.5毫米间距的NanoFree芯片级封装(DSBGA),是空间受限类应用的理想选择。
