IS31FL3733A-QFLS4-TR

Overview

The IS31FL3733A-QFLS4-TR is a general-purpose 12x16 LED matrix driver manufactured by Lumissil Microsystems. It features an I2C-compatible interface for programming and control. The device supports individual auto-breath functions for each LED in the matrix. It operates within a supply voltage range of 2.7V to 5.5V and is designed for surface-mount installation in a 48-WFQFN package with exposed pad.

Feature Summary

Supports 12x16 dot matrix LED driving with individual channel control
Integrates individual auto-breath function for dynamic lighting effects
Programmable via standard I2C compatible communication interface

Applications

LED display panels requiring matrix addressing
Automotive intelligent signaling displays
Consumer electronics indicator arrays

Procurement Notes

Verify the specific suffix 'QFLS4-TR' against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the design accommodates the thermal requirements of the exposed pad QFN-48 package. Confirm I2C address settings match the system bus configuration before integration.

Selection Notes

Select this component when a high-density LED matrix solution with integrated dimming and breath control is required. It is suitable for applications needing precise current regulation without external switching components. Consider the I2C interface compatibility with the host microcontroller and the available PCB space for the 6mm x 6mm footprint.

Part Context

This part belongs to the IS31FL3733 series of LED matrix drivers from Lumissil Microsystems. It is designed as a cost-effective solution for replacing multiple discrete driver ICs in compact display applications. The series typically includes variants like the IS31FL3733B, which may offer updated features or performance characteristics while maintaining pin compatibility.

Replacement Considerations

The IS31FL3733B-QFLS4-TR is a documented variant within the same family. Verify if the B-substitution meets all electrical and functional requirements of the original design. Check for any differences in register maps or timing specifications between the A and B versions.
