XA4202 Datasheet | XINNA SEMI

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 Description The XA4202 is a plete 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. 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 HX6202 automatically enters a low current sleep mode, dropping the battery drain current to 4µA. After the...
