® ISL6297 Data Sheet March 20, 2007 FN9215.1 Li-ion/Li Polymer Battery Charger The ISL6297 is a Dual-Mode Lithium Ion battery charger optimized for cellular phone travel charger applications.

It uses Intersil’s patent-pending dual-mode charge technology to minimize the heat normally generated in a linear charger.

By minimizing the heat generation, the ISL6297 can be placed inside the connector of the travel charger to completely remove the influence of the adapter cable on the charging perform

ISL6297 Features

* include improved accuracy, pre-charge circuit verification, and enhanced LED indicator function. Working with a current-limited AC/DC converter, the dualmode charger charges a Li-ion battery with the same current profile as a traditional linear charger. The constant charge current is determined by t
