ISL9220IRTZEVAL1Z
描述
The ISL9220IRTZEVAL1Z evaluation board is used to evaluate 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 a 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 a thermally enhanced QFN package.
