ISL6292B Datasheet Li-ion/li Polymer Battery Charger

Manufacturer: Renesas

Overview: ISL6292B Li-ion/Li Polymer Battery Charger The ISL6292B uses 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 pletely remove the influence of the adapter cable on the charging performance. 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 the current limit of the ac/dc converter. The constant output voltage is fixed at 4.2V. When the battery voltage is below 2.8V, the charger preconditions the battery with a low trickle-charge current. The charge status is indicated by a tri-color LED. A safety timer prevents charging a dead battery for an excessively long period.

Key Features

  • a thermal foldback function that automatically reduces the charge current when the internal die temperature exceeds a 100°C limit to prevent further temperature rise. This function removes the concern of thermal failure in the targeted space-limited.
