DATASHEET ISL9205, ISL9205A, ISL9205B, ISL9205C, ISL9205D Li-ion Battery Charger FN9252 Rev 4.00 Dec 20, 2018 The ISL9205, ISL9205A, ISL9205B, ISL9205C, and ISL9205D are integrated single-cell Li-ion or Li-polymer chargers 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 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). The charge current during the Constant Current phase is determined by the external resistor connected to the IREF pin.
