IS32FL3268-QWLA3-TR

Overview

The IS32FL3268-QWLA3-TR is an LED driver IC featuring a 24-output linear shift register with PWM dimming and SPI interface. It operates within a voltage range of 2.7V to 5.5V and supports up to 51mA output current per channel. The device is housed in a 40-WFQFN (6x6) package, designed for surface mount installation. It includes integrated thermal shutdown protection and is qualified to AEC-Q100 standards for automotive reliability.

Feature Summary

Integrates a 24-channel linear shift register with independent PWM dimming control for precise LED brightness management.
Supports serial communication via SPI interface for simplified data transmission and configuration.
Includes built-in thermal shutdown protection to ensure safe operation under high-temperature conditions.

Applications

Automotive interior ambient lighting systems
Vehicle exterior intelligent signaling displays
High-pixel count matrix LED drivers

Procurement Notes

Verify the specific suffix QWLA3 against the manufacturer's official datasheet to confirm pinout and packaging dimensions. Ensure the design accounts for the 40-pin WFQFN thermal pad requirements for adequate heat dissipation. Confirm AEC-Q100 qualification status matches the target automotive application grade before finalizing procurement.

Selection Notes

Select this component when a high-density LED driver with SPI control is required for automotive environments. It is suitable for designs needing 24 independently controllable channels with linear current regulation. Consider the 6x6mm package size for space-constrained PCB layouts requiring robust thermal performance.

Part Context

This part belongs to Lumissil's IS32FL series of LED display drivers, optimized for automotive applications. The series focuses on providing reliable illumination control solutions that meet strict automotive quality standards. It complements other Lumissil products used in vehicle lighting and signaling systems.

Replacement Considerations

Check for direct substitutes within the IS32FL series or compatible LED drivers from other manufacturers that offer similar channel counts and SPI interfaces. Verify pin compatibility and thermal characteristics before substitution.
