单灯显示单节充电管理IC

SL1051 是一款专门为高精度的线性锂电池充器而设计的电路，非常适合那些低成本、便携式充电器使用。它集高精度预充电、恒定电流充电、恒定电压充电、电池状态检测、温度监控、充电结束低泄漏、充电状态指示等性能于一身，可以广泛地使用于PDA、移动电话、手持设备等领域。SL1051 通过检测电池电压来决定其充电状态：预充电、恒流充电、恒压充电。当电池电压小于阈值电压 VO(MIN)时，处于预充电状态，以较小的电流对电池进行充电，预充电的电流可以通过外部电阻进行调整。预充电使电池电压达到 VO(MIN) 后，进入恒定电流充电的快速充电状态,充电电流可以通过外围电阻调整，恒定电流充电使电池电压上升到恒定电 ·单节锂离子或锂聚合物电池充电器的理想控制电路；\r\n·高于1%的电压精度；\r\n·预充电过程，用户可改变预充电电流；\r\n·恒定电流充电，充电电流可调；\r\n·恒定电压充电过程；\r\n·自动再充电过程；\r\n·充电过程中的温度监控；\r\n·LED 充电状态指示；\r\n·电池不正常状态的检测；\r\n·电源电压低时，处于低功耗的Sleep 模式，电池漏电流极小；\r\n·极少的外围元器件；\r\n·小型化的MSOP8/SOP8 封装；\r;
