Linear Single Cell Li-Ion Battery Charger IC with Dual Input Supply

General Description The RT9502 is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications. The RT9502 is capable of being powered up from AC adapter and USB (Universal Serial Bus) port inputs. The RT9502 can automatically detect and select the AC adapter

单节锂离子电池双输入线性充电器

RT9502 是适合便携式应用的全集成、低成本的单节锂离子电池充电 IC ，它既可用交流适配器供电，也可用USB接口进行供电，而且会自动的对这两种输入进行检测并从中选择合适的输入作为充电电源。当两个输入都不存在时，RT9502即自动进入睡眠模式。RT9502采用优化的方式完成充电任务，可自动选择预充模式、快充模式和恒压模式进行充电操作。当充电电流降低到预设的充电电流时，充电过程自动终止。当电源来自 USB 接口时，充电电流可在 100mA 和 500mA 之间进行选择。当使用交流适配器进行充电时，充电电流可用外部电阻进行调节，最大值可达 1A 。它内部的热回馈电路可对内核温度进行调节，使得它在 • 自动输入选择\n• 交流适配器输入端最高耐压为 18V\n• 恒定可选 100mA 和 500mA USB 充电电流\n• 内部集成 P-MOSFET\n• 交流适配器电源正常指示\n• 充电状态指示\n• 欠压保护\n• 过压保护\n• 自动复充\n• 电池温度监测\n• 小型10引脚 WDFN 封装\n• 热回馈优化充电速率\n• 符合 RoHS 规范，不含卤素;
