Overview
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.
When the adapter output is a current-limited voltage source and the current limit is smaller than the programmed constant current of the IC, the ISL9205 operates as a pulse charger where the charge current is determined by the current limit of the AC adapter during the Constant Curren...
