Description
Support is limited to customers who have already adopted these products.
The ISL9220 and ISL9220A are cost-effective and versatile battery chargers for 1-cell and 2-cell Li-ion and Li-Polymer-based portable applications. The device features synchronous PWM technology, maximizing power efficiency, thus minimizing charge time and heat. The 1.2MHz switching frequency allows use of small external inductors and capacitors. A simple charge current programming method is provided. External resistors program the fast charge and end-of-charge currents. The two status outputs can be used to drive LEDs, or can be connected to a host processor. A programmable charge timer provides the ability to detect defective batteries, and provides a secondary method for detecting charge termination. A thermistor interface is provided for battery presence detection and for temperature-qualified charging conditions. Additional features include preconditioning of an over-discharged battery, automatic recharge, and a thermally enhanced QFN package.
