首鼎 HXN-XIAA 单节锂电池充电管理IC
Description :
The HXN-XIAA is a complete battery charger controller for one (4.2V) cell lithium-ion battery.The HXN-XIAA 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 HXN-XIAA 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 HXN-XIAA is available in the 8-lead SO Package.
