概览

FAN54015 IC 为单体（1S）锂离子电池和锂聚合物电池提供完全集成的USB 电源充电功能。 该 IC 包括过压保护、高效率 DC-DC 同步转换器，在 4.2V 时，输出为 1.45 A，足以为高达 2000 mAh 的锂离子电池和锂聚合物电池充电，充电速率为 0.7 C。
FAN54015 提供三相电池充电功能： 调节、恒定电流和恒定电压，保护电池并最大限度地提高运行时间。 如果芯片裸片温度监视器达到 120℃，充电电流降低。器件受 IC 控制，从而可编程充电操作模式和参数。
IC 封装在 1.96毫米×1.87毫米，20 焊点 WLCSP 封装内。

  • 通过 USB 电源对电池充电/无需外部电源适配器
  • 1.45 A 充电电流，足以为高达 2000 mAh 的锂离子电池和锂聚合物电池充电，充电速率为 0.7 C
