Li-ion/Li Polymer Battery Charger

Features

The ISL6292B uses Intersil’s patent-pending dual-mode

charge technology to minimize the heat in a linear charger.

The ISL6292B is a modification of the original ISL6292 and

is optimized for cellular phone travel charger applications.

The low-heat generation feature of the dual-mode charger

enables the charger IC to be placed inside the connector of

the travel charger to completely remove the influence of the

adapter cable on the charging performance.

• Complete Charger for Single-Cell Li-ion Batteries

• Integrated Pass Element and Current Sensor

• No External Blocking Diode Required

• Very Low Thermal Dual-Mode Operation

• 1% Voltage Accuracy with Remote Sense

• Programmable Current Limit up to 1.5A

• Programmable End-of-Charge Current

• Programmable Safety Timer

Working with a current-limited ac/dc converter, the dual-

mode charger charges a Li-ion battery with the same current

profile as a traditional linear charger. The constant charge

current is determined by the current limit of the ac/dc

converter. The constant output voltage is fixed at 4.2V. When

the battery voltage is below 2.8V, the charger preconditions

the battery with a low trickle-charge current. The charge

status is indicated by a tri-color LED. A safety timer prevents

charging a dead battery for an excessively long period.

• Drives a Tri-Color LED

• Charge Current Thermal Foldback

• NTC Thermistor Interface for Battery Temperature Monitor

• Two-Level Ambient Temperature Setting

• Guaranteed to Operate at 2.65V After Start-Up

• Ambient Temperature Range: -20°C to 70°C

• Thermally-Enhanced QFN Packages

• QFN Package:

- Compliant to JEDEC PUB95 MO-220

QFN - Quad Flat No Leads - Package Outline

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

The ISL6292B also features a thermal foldback function that

automatically reduces the charge current when the internal

die temperature exceeds a 100°C limit to prevent further

temperature rise. This function removes the concern of

thermal failure in the targeted space-limited applications. An

ambient temperature monitoring circuit allows users to set

two separate temperature limit levels, one for during charge

and one for not during charge. The thermally-enhanced QFN

package further improves the thermal performance of the

ISL6292B in space-limited applications.

• Pb-Free Available (RoHS Compliant)
