IS32FL3248-LQLA3-TR

Overview

The IS32FL3248-LQLA3-TR is a 48-channel LED driver IC designed for backlight applications and LED matrix control. It features linear constant-current output with 16-bit PWM dimming capability. The device operates within an eLQFP-64 package (10mm x 10mm) and supports SPI interface for dimming control. Output current per channel is specified at 24.8 mA to 33.8 mA depending on configuration.

Feature Summary

Provides 48 independent channels for precise LED intensity management
Integrates 16-bit PWM resolution for smooth brightness transitions
Supports SPI interface for efficient digital dimming control

Applications

Automotive display backlighting systems
High-resolution LED matrix displays
Industrial indicator panels requiring uniform illumination

Procurement Notes

Verify the specific suffix LQLA3 against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the ordering quantity aligns with the tape-and-reel packaging specifications provided by Lumissil Microsystems. Cross-reference the AEC-Q100 qualification status if automotive reliability is required for the final assembly.

Selection Notes

Select this component when high channel count and fine grayscale resolution are necessary for backlight uniformity. The 16-bit PWM offers superior flicker-free performance compared to lower-resolution alternatives. Consider the eLQFP-64 footprint for PCB layout constraints and verify thermal dissipation requirements for the target application environment.

Part Context

This part belongs to the IS32FL series of LED drivers from Lumissil Microsystems, optimized for complex lighting architectures. It complements other series like IS32LT for linear driving or IS31FL for matrix addressing. The design focuses on reducing external component count while maintaining high precision in automotive and industrial signaling applications.

Replacement Considerations

Check for IS32FL3248-QWLA3-TR as a potential variant with different packaging. Verify compatibility with existing SPI protocols and current sourcing capabilities before substitution.
