数据: 具有直接电池连接功能的 bq27510-G3 系统端 Impedance Track™ 电量监测计 数据表 (Rev. A)
德州仪器(TI)生活控制器离子电池组的电量计量。此器件只需很少的系统微处理器固件开发.bq27510-Q3驻留在系统主板上,并且管理一个嵌入式电池(不可拆卸)或一个可拆卸电池组。
bq27510-G3使用获得专利的Impedance Track™算法来进行电量监测,可提供剩余电池电量(mAh),充电状态(%),续航时间(min。),电池电压(mV),温度(°C)和运行状况(%)等信息。
使用bq27510-G3进行电池电量监测时,只需将PACK +(P +),PACK-(P-)以及选装的热敏电阻(T)连接至一个可拆卸电池组或嵌入式电池电路。
