 Description
The VS8203 is a complete battery charger
controller for one (4.2V) cell lithium-ion battery.
The VS8203 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 4.2V. When the input
supply is removed, the VS8203 automatically
enters a low current sleep mode.
The VS8203 is available in the SOP-8L package.
