ME4086 24V Input Voltage Switch Mode Battery Charger ME4086 General Description The ME4086 is a complete battery charger controller for one (4.2V/4.35V) or two (8.4V) 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/4.35V) or two (8.4V) 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.
