PW4054 是一款性能优异的单节锂离子电池恒流/恒压线性充电器。PW4054 适合给 USB 电源以及适配器电源供电。基于特殊的内部 MOSFET 架构以及防倒充电路， PW4054 不需要外接检测电阻和隔离二极管。当外部环境温度过高或者在大功率应用时，热反馈可以调节充电电流以降低芯片温度。充电电压固定在 4.2V，而充电电流则可以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的 1/10，芯片将终止充电循环。当输入电压断开时， PW4054 进入睡眠状态，电池漏电流将降到 1uA 以下。 PW4054 还可以被设置于停机模式，此时芯片静态电流降至 25uA。PW4054 还包括其他特性：欠压锁定，自动再充电和充电状态标志。PW4054 采用 SOT23-5L 封装配合较少的外围原件使其非常适用于便携式产品

The PW2601 is a charger front-end integrated circuit designed to provide protection to Li-ionbatteries from failures of charging circuitry. The device monitors the input voltage, battery voltageand the charging current to make sure all three parameters are operated in normal range. Thedevice will switch off internal MOSFET to disconnect IN to OUT to protect load when any of inputvoltage, output current exceeds the threshold. The Over temperature protection (OTP) functionmonitors chip temperature to protect the device. The PW2601 also can protect the system’sbattery from being over charged by monitors the battery voltage continuously. The deviceoperates like a linear regulator, maintaining a 5.1V output with input voltages up to the input overvoltage threshold.The PW2601 is available in DFN-2x2-8L package. Standard products are Pb-free and Halogenfree
