Texas Instruments bq27441-G1系统侧Impedance Track™ 电量监测计
Texas Instruments bq27441-G1系统侧Impedance Track™电量监测计是易于配置的微控制器外设，为单节锂离子电池提供系统侧电量监测。器件仅需最少程度的用户配置和系统微控制器固件开发。bq27441-G1采用获得专利的Impedance Track™算法进行电量计量，并提供剩余电池容量（mAh）、当前充电状态（%）和电池电压（mV）等信息。bq27441-G1的电池电量计量仅需连接PACK+ (P+)和PACK- (P-)即可计量可拆卸电池组或嵌入式电池电路。极小的12引脚2.5mm×4mm SON封装是空间受限应用的理想选择。
