德州仪器 (TI) bq27742-G1 器件是一款电量监测计，适用于单节锂离子电池组。此电量计使用已获专利的 Impedance Track™技术，可预测剩余电池电量和系统运行的速率、温度和老化补偿并且具有最高精度。此器件还含有一个完全集成的高侧保护器，无需单独的锂离子保护电路即可对是否存在过压、欠压、充电过流、放电过流和放电短路条件进行全套高精度故障检测。硬件保护功能提供了内置数据闪存可编程功能，方便针对不同的终端设备需求重新配置现有器件。
这款电量监测计可提供剩余电池电量 (mAh)、充电状态 (%)、续航时间（分钟）、电池电压 (mV)、电流 (mA) 和温度 (°C) 等信息，以及整个电池使用寿命期间记录的重要参数。此器件还支持中断主机，指示检测到各种重要的故障条件并汇报给系统。
DSBGA 是 15 焊球封装 (2.78mm × 1.96mm)，非常适合空间受限的 应用。
