XA4202 - Standalone Li-Lon Switch Mode Battery Charger

General Description

The XA4202 is a complete battery charger controller for one (4.2V) cell lithium-ion battery.

The XA4202 provides a small, simple and efficient solution to fast charge Li-ion battery.

An external sense resistor sets the charge current with high accuracy.

Key Features

  • Input Supply Range: 4.7V-6V High Efficiency Current Mode PWM Controller End - Charge - Current Detection Output Constant Switching Frequency for Minimum Noise ±1% Charge Voltage Accuracy Automatic Battery Recharge Automatic Shutdown When Input Supply is Removed Automatic Trickle Charging of Low Voltage Batteries Battery Temperature Sensing Stable with Ceramic Output Capacitor 8-Lead SO Package.
