ISL9220IRTZEVAL1Z

Switching Charger Evaluation Board for 1-Cell Li-ion Batteries

Description

The ISL9220IRTZEVAL1Z is an evaluation tool for the ISL9220 battery charger for 1-cell Li-ion and Li-Polymer batteries.

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 host processor. A programmable charge timer provides the ability to detect defective batteries, and provides a secondary method of 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 thermally enhanced QFN package.
