500mA 线性锂离子电池充电器

SD8055是一款完整的单节锂离子电池充电器，带电池正负极反接保护，采用恒定电流/恒定电压线性控制。其SOT封装与较少的外部元件数目使得SD8055成为便携式应用的理想选择。SD8055可以适合USB电源和适配器电源工作。\r\n\r\n 由于采用了内部PMOSFET架构，加上防倒充电路，所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节，以便在大功率操作或高环境温度条件下对芯片温度加以限制。充满电压固定于4.2V，而充电电流可通过一个电阻器进行外部设置。当电池达到4.2V之后，充电电流降至设定值1/10， SD8055将自动终止充电。\r\n\r\n 当输入电压 ·锂电池正负极反接保护；\r\n·高达500mA的可编程充电电流；\r\n·无需MOSFET、检测电阻器或隔离二极管；\r\n·用于单节锂离子电池\r\n·恒定电流/恒定电压操作，并具有可在无过热危险的情况下实现充电速率最大化的热调节功能；\r\n·可直接从USB 端口给单节锂离子电池充电；\r\n·最高输入可达9V；\r\n·精度达到±1%的4.2V 预设充电电压；\r\n·自动再充电；\r\n·1 个充电状态开漏输出引脚；\r\n·C/10 充电终止；\r\n·待机模式下的供电电流为40uA；\r\n·2.9V涓流充电；\r\n·软启动限制了浪涌电流；\r\n·采用5 引脚SOT-;
