HP4054S5-42

HP4054 500mA, Single Li-ion Battery Charger GENERAL DESCRIPTION FEATURES The HP4054 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 500mA Under Voltage Lockout Protection 150mV(Typ.) Automatic Recharge Threshold ⚫ ⚫ ⚫ Charge Status Output Pin 2.9V Trickle Charge Threshold Soft-Start Limits Inrush Current The HP4054 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 HP4054 automatically enters a low current state, dropping the battery drain current to less than 0.1uA.

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. 2 GND Ground 3 BAT O Power ground Charge Current Output. Provides charge current to the battery and regulates the final float voltage to 4.2V or 4.35V. 4 VCC Power Power Supply Charge current setting, charge current monitor and shut down pin. The 5 PROG O charging current is given by IBAT= 1000/RPROG(A). Please choose 1% precision resistor for RPROG. The chip will be shutdown when PROG pin floating.
