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

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
