HX6202 Datasheet | Hexin Semiconductor

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 plete 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...
