The PW4556 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 or
4.35V, 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
