the sd6401e is a complete battery charger controller for two (8.4v) cells lithium-ion batteries.the sd6401e provides a small, simple and efficient

solution to fast charge li-ion battery. an external sense resistor sets the charge current with high accuracy.supply is removed, the sd6401e automatically enters a low current sleep mode. an internal resistor divider and precision

reference set the final float voltage.the sd6401e is available in the sop-8l package.
