Li-ion/Li Polymer Battery Charger

The ISL6292B uses Intersil’s patent-pending dual-mode charge technology to minimize the heat in a linear charger. The ISL6292B is a modification of the original ISL6292 and is optimized for cellular phone travel charger applications. The low-heat generation feature of the dual-mode charger enables the charger IC to be placed inside the connector of the travel charger to completely remove the influence of the adapter cable on the charging performance.
