ISL6297 - Li-ion/Li Polymer Battery Charger

Description

PIN # 1, 15, 16 2 3 4 5 6 7 8 PIN NAME VIN GRN RED TIME GND DT EN V2P9 DESCRIPTION VIN is the input power source.

It is recommended to have a 1Ω resistor in series with the input decoupling capacitor to prevent an over-shoot voltage when the input cable is plugged in.

Open-drain LED drive pin.

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 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.

® 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 performance. The ISL6297 is an enhancement of the original ISL6292B. New features include improved accuracy, pre-charge circuit verification, and enhanced LED indicator function.
