IS31FL3766-QFLS4-TR

Overview

The IS31FL3766-QFLS4-TR is a linear LED driver IC manufactured by Lumissil Microsystems, designed for dot matrix applications. It features 18 outputs with a maximum current of 40mA per channel and supports I2C and PWM dimming interfaces. The device operates within a supply voltage range of 2.7V to 5.5V and functions across a temperature range of -40°C to +125°C. Packaged in a 32-WFQFN (4x4mm) exposed pad format, it utilizes a tape and reel packaging configuration.

Feature Summary

• Supports configurable 18x6 dot matrix LED configurations
• Integrates I2C programming interface with PWM dimming capability
• Provides individual channel current control for precise brightness adjustment

Applications

• Dot matrix LED displays
• Automotive intelligent signaling systems
• Consumer IoT lighting modules

Procurement Notes

Verify the specific suffix QFLS4 against the manufacturer's latest datasheet to confirm package dimensions and pinout compatibility. Ensure the I2C address settings align with system bus requirements. Confirm RoHS compliance status through official documentation before integration into regulated environments.

Selection Notes

Select this component when a compact solution for high-density LED matrices is required. The linear topology suits low-voltage applications where efficiency is secondary to cost and simplicity. Verify that the 40mA output current meets the forward current requirements of the selected LEDs without external heat sinking.

Part Context

This part belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems, which focuses on matrix display solutions. The series integrates control logic and constant current sinks into a single small-footprint package, reducing board space and component count compared to discrete driver designs.

Replacement Considerations

Check Lumissil's official substitution guide for direct equivalents. Cross-reference pinouts and electrical characteristics with other IS31FL37xx variants if available.
