Description
The ISL9203R5220 is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2.4V. This charger is designed to work with various types of AC adapters.
The ISL9203R5220 operates as a linear charger when the AC adapter is a voltage source. The battery is charged in a CC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor up to 1.5A. The ISL9203R5220 can also work with a currentlimited adapter to minimize the thermal dissipation, in which case the ISL9203R5220 combines the benefits of both a linear charger and a pulse charger.
The ISL9203R5220 features charge current thermal foldback to guarantee safe operation when the printed circuit board is space limited for thermal dissipation. Additional features include preconditioning of an over-discharged battery and thermally enhanced DFN package.
