bqTINY™系列是高度集成的锂离子和锂聚合物线性充电管理器件,面向空间有限的便携式应用。 bqTINY™系列采用小型封装,提供集成的powerFET和电流传感器,反向阻断保护,高精度电流和电压调节,充电状态和充电终止。
bqTINY™分三个阶段为电池充电:调节,恒定电流和恒定电压。根据最小电流终止充电。内部充电定时器为充电终止提供备用安全功能。如果电池电压低于内部阈值,bqTINY™会自动重启充电。当移除V CC 电源时,bqTINY™会自动进入睡眠模式。
除了标准功能外,不同版本的bqTINY™还提供多种附加功能。这些包括用于检测热电池组或冷电池组的温度传感输入; power good( PG )输出,表示存在有效输入功率; TTL电平充电使能输入(CE),用于禁用或启用充电过程;以及用于禁用或启用快速充电定时器和充电终止的TTL电平定时器和终端使能(TTE)输入。
