GENERAL DESCRIPTION
The HP4060 series of devices are highly integrated Li-Ion
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 or 4.4V,
and 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 HP4060 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 HP4060 will shut off, only 40nA leakage
current coming from battery at sleep mode when
ambient temperature is 85℃, so it can save energy and
improve standby time.
The HP4060 is available in a small package with
TDFN1X1-6L. Standard product is Pb-Free and Halogen
free.
