IS31FL3736-QFLS4-TR

Overview

The IS31FL3736-QFLS4-TR is a general-purpose LED matrix driver manufactured by Lumissil Microsystems. It supports a 12x8 dot matrix configuration with a 1/12 cycle rate and features individual auto-breath functions for each LED. The device operates on a supply voltage range of 2.7V to 5.5V and provides an output current of 45mA per channel. It utilizes an I2C compatible interface for programming and control. The component is housed in a QFN-40 package measuring 5.0mm x 5.0mm.

Feature Summary

Supports 12x8 LED matrix configurations with individual auto-breath functionality
Programmable via standard I2C compatible interface
Linear LED driver topology with constant current outputs

Applications

LED display panels requiring matrix addressing
Automotive interior lighting systems
Industrial indicator arrays

Procurement Notes

Verify the specific suffix -QFLS4-TR against official Lumissil documentation to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into regulated assemblies.

Selection Notes

Select this component when a fixed 12x8 matrix layout is required without external multiplexing complexity. Ensure the design accommodates the 45mA per-channel current capability and that the host controller supports the necessary I2C communication protocol for register configuration.

Part Context

This part belongs to the IS31FL3736 series, which focuses on simplified LED matrix driving solutions. It serves as a dedicated driver within Lumissil's portfolio for applications needing direct LED control without complex microcontroller overhead for scanning logic.

Replacement Considerations

The IS31FL3737B-QFLS4-TR is a documented alternative offering a 12x12 matrix configuration. Verify pin compatibility and software register mapping differences before substituting, as the increased matrix size may require PCB layout adjustments.
