电源电路

AP4056 是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其底部带有散热片的 SOP8 封装，与较少的外部元件使得 AP4056 成为便携式应用的理想选择。AP4056可以适合 USB 电源和适配器电源工作。\n\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。充电电压固定于 4.2V，而充电电流可通过一个电阻器进行外部设置。当充电电流在达到最终浮充电压之后降至设定值 1/1 • 高达 1000mA 的可编程充电电流\n• 无需 MOSFET、检测电阻器或隔离二极管 \n• 用于单节锂离子电池、采用 SOP 封装的完整线性充电器\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精度达到±1.5%的4.2V 预设充电电压\n• 用于电池电量检测的充电电流监控器输出\n• 自动再充电\n• 充电状态双输出、无电池和故障状态显示 \n• C/10 充电终止\n• 待机模式下的供电电流为 55uA\n• 约2.8V涓流充电器件版本\n• 软启动限制了浪涌电流\n• 电池温度监测功能\n• 采用8引脚SOP 带底部散热片封;
