Description
The HX6202 is a complete battery charger controller for one (4.22V) cell lithium-ion battery. The HX6202 provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy. An internal resistor divider and precision reference set the final float
voltage to 4.22V per cell with ±1% accuracy.
When the input supply is removed, the HX6202 automatically enters a low current sleep...
