HX6202

HXH6X2100201 Standalone Li-Lon Switch Mode Battery Charger 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 SOP Package Application 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 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...
