IS32FL3209-QWLA3-TR

Overview

The IS32FL3209-QWLA3-TR is an automotive-grade LED driver IC featuring 18 constant current channels. It supports PWM dimming with selectable frequencies of 24 kHz or 4 kHz and includes DC scaling for white balance adjustment. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes I2C control. Packaged in a 28-WFQFN (5x5) format, it is designed for high-reliability applications requiring precise current regulation.

Feature Summary

Provides 18 independent constant current output channels for uniform LED illumination
Supports dual-frequency PWM dimming modes at 24 kHz and 4 kHz for flexible system integration
Integrates DC scaling capability to enable precise white balance adjustments across channels

Applications

Automotive interior ambient lighting systems
Vehicle dashboard and instrument cluster backlighting
High-reliability industrial LED indicator arrays

Procurement Notes

Verify the specific suffix QWLA3 corresponds to the 28-WFQFN (5x5) package variant. Confirm AEC-Q100 qualification status for automotive deployment requirements. Ensure I2C interface compatibility with the host controller. Check moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when 18 individually controllable constant current outputs are required within a compact footprint. Choose over linear drivers if PWM dimming flexibility and white balance correction are necessary. Consider alternative packages like eTSSOP if board space constraints differ from the WFQFN form factor.

Part Context

This part belongs to the IS32FL3209 family of automotive LED drivers from Lumissil Microsystems. The family shares core functionality but varies by package type and pinout configuration. The QWLA3 suffix specifically denotes the 28-pin WQFN package variant optimized for surface-mount assembly.

Replacement Considerations

The IS32FL3209-ZLA3-TR serves as a functional substitute using the 28-eTSSOP package. Verify pin-to-pin compatibility and thermal performance differences between the WFQFN and eTSSOP footprints before substitution.
