IS31FL3741-QFLS4-TR

Overview

The IS31FL3741-QFLS4-TR is a linear LED driver IC manufactured by Lumissil Microsystems. It features 9 constant current outputs, each capable of delivering up to 38mA. The device operates on a supply voltage range of 2.7V to 5.5V and supports I²C and PWM dimming interfaces with an I²C frequency of 1MHz. Packaged in a 60-WFQFN (7x7mm) exposed pad surface-mount package, it is rated for an operating temperature range of -40°C to +125°C.

Feature Summary

Linear topology with no internal switches for high-density illumination applications
Supports I²C and PWM dimming control interfaces
Automotive-grade reliability with extended temperature rating

Applications

High-density automotive interior lighting
Matrix LED display drivers
General-purpose LED illumination systems

Procurement Notes

Verify the specific suffix QFLS4-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Ensure the design accounts for the 60-WFQFN thermal requirements and I²C bus constraints. Confirm RoHS compliance status via the latest datasheet before procurement.

Selection Notes

Select this component when a low-profile solution with multiple constant current channels is required for automotive or industrial environments. The linear architecture suits applications where switching noise must be minimized. Verify that the 38mA per channel output meets the load requirements without exceeding thermal limits in the 60-QFN package.

Part Context

This part belongs to the IS31FL37xx series of LED lighting drivers from Lumissil Microsystems. These drivers are designed for FXLED applications, supporting wide ranges of LEDs with EMI noise reduction technology. The IS31FL3741 variant specifically provides 9 channels, distinguishing it from other family members with different channel counts like the IS31FL3742 or IS31FL3748.

Replacement Considerations

Publicly confirmed direct substitutes for this specific part number are not available in the provided source data. Designers should consult Lumissil Microsystems for updated replacement recommendations if this component becomes obsolete.
