The HC8023 is a complete switching battery charger for one (4.2V) cell lithium-ion battery.
The HC8023 provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy.
The maximum charge current which programmed by a resistor is up to 1.2A. An internal resistor divider and precision reference set the final float voltage to 4.2V. When the input supply is removed, the HC8023 automatically enters a low current sleep mode.
