ISL9205 Overview
The low operating voltage allows the charger to work with a variety of AC adapters. The ISL9205 family operates as a linear charger when the AC adapter is a voltage source. The battery is charged in a standard Li-ion charge profile, that is, a Constant Current phase followed by a Constant Voltage phase (CC/CV).
