LM3658是一种单芯片充电器IC设计为手持式应用。 它可以安全充电和维护一个单细胞，从一个交流适配器或USB电源的聚合物电池操作。 的USB / AC输入功率源的选择是自动的。 目前两间电力来源，交流电源具有优先权。 从AC墙上适配器允许充电电流从50 mA至1000 mA的工作时，充电电流通过一个外部电阻编程。 当电池充电，使用USB供电，充电电流为100 mA或500 mA引脚可选的。 终止电压控制在4.2V的范围内± 0.35％。

LM3658需要很少的外部元件和集成内部功率FET，反向电流保护和电流感应。 内部功率FET，热调节，以获得最有效的收费率对于一个给定的环境温度。

LM3658经营五种模式：资格预审模式，恒流模式，恒压模式，顶部关闭模式和维护模式。 此外，该充电器IC作为“LDO模式”，墙壁上的AC适配器连接时并没有电池是目前的线性稳压器。 获得最佳的电池管理是通过热调节，电池温度测量和多个安全计时器。 LM3658提供了LED状态指示或连接到GPIO的两个漏极开路输出。
