HP4056E8-42

HP4056 1A, Single Li-ion Battery Charger GENERAL DESCRIPTION FEATURES The HP4056 is a complete constant-current/ constant voltage linear charger for single cell Lithium-Ion batteries. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V or 4.35V, and the charge current can be programmed externally with a single resistor.    Programmable Charge Current Up to 1A Under Voltage Lockout Protection 150mV(Typ.) Automatic Recharge Threshold    Charge Status Output Pin 2.9V Trickle Charge Threshold Soft-Start Limits Inrush Current APPLICATIONS Feature Phone MP3/MP4 Players Electric Toy Bluetooth, wireless handsets Others portable electronic device The HP4056 automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached.      When the input supply (wall adapter or USB supply) is removed, the HP4056 automatically enters a low current state, dropping the battery drain current to less than 0.1uA.

The higher threshold is 0.8*VCC and lower threshold is 0.45*VCC. If it is useless, please pull it low to ground. 2 PROG Charge current setting, charge current monitor and shut down pin. The charging current is given by I BAT = 1000/R PROG (A). Please choose 1% precision resistor for R PROG . 3 GND Ground 4 VCC Power Supply 5 BAT Charge Current Output. Provides charge current to the battery and regulates the final float voltage to 4.2V or 4.35V. 6 STDb 7 CHGb 8 CE Charge termination indicated pin. When charge is terminated, it is pulled low, otherwise it is high impedance. Open-Drain Charge Status Output. When the battery is charging, the CHGb pin is pulled low. When the charge cycle is completed or VCC is removed, the CHGb is forced high impedance. Charge enable pin. High is enable, low is disable.
