Standalone Li--Lon Switch Mode Battery Charger
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 pider 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 mode,
dropping the battery drain current to 4μA. After the
charge cycle ends, if the battery voltage drops
below 4.05V per cell, a new charge cycle will
automatically begin.
The HX6202 is available in the 8-lead SOP
Package.
