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...
