1A锂电池保护芯片

CX4056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/MSOP8封装与较少的外部元件数目使得CX4056成为便携式应用的理想选择。CX4056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1/10时，CX4056将自动终止充电循环。\r\n\r\n 当输入电压（交流 • 高达1000mA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、采用SOP封装的完整线性充电器\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\r\n• 精度达到±1%的4.2V预设充电电压\r\n• 用于电池电量检测的充电电流监控器输出\r\n• 自动再充电\r\n• 充电状态双输出、无电池和故障状态显示\r\n• C/10充电终止\r\n• 待机模式下的供电电流为55uA\r\n• 2.9V涓流充电\r\n• 软启动限制了浪涌电流\r\n• 电池温度监测功能\r\n• 采用8引脚SOP;
