HP4059D6-42Y

HP4059 300mA Single Cell Li-ion Battery Charger 0.1mA Termination, 45nA Battery Leakage Current GENERAL DESCRIPTION FEATURES The HP4059 series of devices are highly integrated Li-Ion Charging - 1% Charge Voltage Accuracy - 5% Charge Current Accuracy - Support Application for Very Low Charge Currents – 1mA to 300mA - Support minimum 0.1mA Charge Termination Current - 45nA Maximum Battery Output Leakage Current @ and Li-Pol linear chargers targeted at small capacity battery for portable applications. It is a complete constant-current/ constant voltage linear charger. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a good thermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V/4.35V/4.4V, and 0℃~85℃ the charge current can be programmed externally with - a single resistor. The charger function has high accuracy Others - Output Short-Circuit Protection - Soft-Start Limits Inrush Current - Charge Status Output Pin - Automatic Recharge current and voltage regulation loops and charge termination. The HP4059 automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached. High Voltage Chemistry Support: up to 4.4V APPLICATIONS  Fitness Accessories When the input supply (wall adapter or USB supply) is  Smart Watches removed, the HP4059 will shut off, only 40nA leakage  Bluetooth Handsets current coming from battery at sleep mode when  Wireless Low-Power Handheld Devices ambient temperature is 85℃, so it can save energy and improve standby time.
