Switching Charger for 1-Cell Li-ion Batteries

ISL9220B

Features

• Highly Integrated Battery Charger IC

• Charges 1 Li-ion or Li-Polymer Batteries

• Up to 2A Charge Current

The ISL9220B is a cost-effective and versatile battery

charger for 1-cell 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.

• Synchronous Buck Topology, with Integrated Power

FETs

• 1.2MHz Switching Frequency

• 0.5% Charge Voltage Accuracy

A simple charge current programming method is

provided. External resistors program the fast charge and

end-of-charge currents.

• Input Current Limit Programmable with One External

Resistor

The two status outputs can be used to drive LEDs, or can

be connected to the host processor.

• Thermistor Interface for Battery Detection and

Temperature Qualified Charging

• Two Status Outputs

A programmable charge timer provides the ability to

detect defective batteries, and provides a secondary

method of detecting charge termination.

• Programmable Charge Safety Timer

• Short-Circuit and Thermal Protection

• Small 4x4mm TQFN Package

A thermistor interface is provided for battery presence

detection, and for temperature qualified charging

conditions.

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

Related Literature

Additional features include preconditioning of an

over-discharged battery, automatic recharge, and

thermally enhanced QFN package.
