    The ME4086 is a complete battery charger controller for one (4.2V) or three (12.6V) cell lithium-ion battery. The ME4086 provides a small, simple and efficient solution to fast charge Li-ion battery. The

ME4086 built in anti current backward function, so the application does not need the blocking diode. An external sense resistor sets the charge current with high accuracy.

    An internal resistor divider and precision reference set the final float voltage to one (4.2V) or three (12.6V) cell with ±1% accuracy. When the input supply is removed, the ME4086 automatically enters a low

current sleep mode, dropping the battery drain current to 3μA.After the charge cycle ends, If the battery voltage drops below one (4.1V) or three (12.2V) cell, a new charge cycle will automatically begin.

    ME4086是一款適用于單電池（4.2V）或三電池（12.6V）鋰離子電池的完整電池充電器控制器。ME4086為鋰離子電池的快速充電提供了一種小型、簡單、高效的解決方案。ME4086內(nèi)置反電流反向功能，因此應(yīng)用不需要阻塞二極管。外部感測電阻器以高精度設(shè)置充電電流。

    內(nèi)部電阻分壓器和精度基準(zhǔn)將最終浮動電壓設(shè)置為一個（4.2V）或三個（12.6V）單元，精度為±1%。當(dāng)輸入電源斷開時，ME4086自動進(jìn)入低電流睡眠模式，將電池漏電流降至3μa。充電周期結(jié)束后，如果電池電壓降至一個（4.1V）或三個（12.2V）電池以下，將自動開始新的充電周期。

ME4086 Typical Application Circuit（典型應(yīng)用電路）:

Note: 1.The dotted part of the box is the input capacitor. When the input voltage is lower than 9V, ceramic capacitor 

can be selected. When the input voltage is higher than 9V, an electrolytic capacitor over 100uF should be added into 

the input. The larger the charging power, the larger the capacity of electrolytic capacitor.

 2. For the hot-swappable application at the BAT pin, it is also necessary to add electrolytic capacitors, it is 

recommended to be 220uF or more.

Note: 1.The Rc and Cc value range of SW to GND, Rc: 0.5 Ω ~ 20 Ω, Cc: 1 nF ~ 100 nF.

 2. For the hot-swappable application at the BAT pin, it is also necessary to add electrolytic capacitors, it is 

recommended to be 220uF or more.
