双输入独立型锂离子电池充电器

LTC®4076 是一款能够从墙上适配器和 USB 输入对单节锂离子电池进行充电的独立型线性充电器。该充电器可在输入端上检测电源，并自动地选择合适的电源用于充电。\n\n 由于采用了内部 MOSFET 架构，因此充电操作无需外部检测电阻器或隔离二极管。内部热反馈电路可调整电池充电电流，以便在高功率工作或高环境温度条件下保持恒定的芯片温度。浮动电压被固定在 4.2V，而充电电流可通过一个外部电阻器来设置。当充电电流在达到最终浮动电压之后降至用户设置的终止门限以下时，LTC4076 将终止充电周期。可将 LTC4076 置于停机模式，从而把 DCIN 电源电流、USBIN 电源电流和电池 • 可从墙上适配器和 USB 输入对单节锂离子电池进行充电\n\n• 输入电源的自动检测和选择\n\n• 采用墙上适配器输入时可编程充电电流高达 950mA\n\n• C/X 充电电流终止\n\n• 热调整功能可在无过热危险的情况下实现充电速率的最大化\n\n• 准确度达 ±0.6% 的预设充电电压\n\n• 停机模式中的 18µA USB 中止电流\n\n• “电源接入”状态输出\n\n• 充电状态输出\n\n• 自动再充电\n\n• 采用外形扁平 (仅高 0.75mm) 的耐热性能增强型 10 引脚 (3mm x 3mm) DFN 封装;
