The ISL9201 is an integrated single-cell Li-ion or Li-polymer charger capable of operating at an input
voltage as low as 2.
5V.
The low operating
voltage allows the charger to work with a variety of AC adapters.
The ISL9201 operates as a linear charger when the AC adapter is a
voltage source.
The battery is charged in a standard Li-ion charge profile, i.
e.
a constant current phase followed be a constant
voltage phase (CC/CV).
The charge current during the constant current phase is...
