ISL9220, ISL9220A

Switching Charger for 1-Cell and 2-Cell Li-ion Batteries

FN6936

Rev 3.00

February 16, 2012

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

• Highly Integrated Battery Charger IC

• Charges 1- and 2-Cell Li-ion or Li-Polymer Batteries

• Up to 2A Charge Current

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.

• Synchronous Buck Topology with Integrated Power FETs

• 1.2MHz Switching Frequency

A simple charge current programming method is provided.

External resistors program the fast charge and end-of-charge

currents.

• 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

• Programmable Charge Safety Timer

• Short-Circuit and Thermal Protection

• Small 4mmx4mm TQFN Package

• -40°C to +85°C Operating Temperature Range

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.
