ISL9220, ISL9220A FN6936
Rev 3.00
February 16, 2012 Switching Charger for 1-Cell and 2-Cell Li-ion Batteries
The ISL9220, ISL9220A is a cost-effective and versatile
battery charger for 1-cell and 2-cell Li-ion and Li-Polymer
based portable applications. Features 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. Charges 1-and 2-Cell Li-ion or Li-Polymer Batteries A simple charge current programming method is provided.
External resistors program the fast charge and end-of-charge
currents. 1.2MHz Switching Frequency Highly Integrated Battery Charger IC Up to 2A Charge Current Synchronous Buck Topology with Integrated Power FETs 0.5% Charge Voltage Accuracy Programmable Input Current Limit with One External
Resistor The two status outputs can be used to drive LEDs, or can be
connected to host processor. Thermistor Interface for Battery Detection and Temperature
Qualified Charging A programmable charge timer provides the ability to detect
defective batteries, and provides a secondary method of
detecting charge termination. Two Status Outputs A thermistor interface is provided for battery presence
detection, and for temperature qualified charging conditions. Programmable Charge Safety Timer Additional features include preconditioning of an
over-discharged battery, automatic recharge, and thermally
enhanced QFN package. Small 4mmx4mm TQFN Package Applications Related Literature PDAs and Smart Phones TB363 вЂњGuidelines for Handling and Processing Moisture
