IS31FL3736A-QFLS4-TR

Overview

The IS31FL3736A-QFLS4-TR is a general-purpose 12x8 LED matrix driver manufactured by Lumissil Microsystems. It features a 1/12 cycle rate and supports individual auto-breath functions for each LED. The device is programmable via an I2C compatible interface, allowing precise control over the display. It operates within a supply voltage range of 2.7V to 5.5V and is housed in a QFN-40 package measuring 5.0mm x 5.0mm.

Feature Summary

Supports 12x8 dot matrix configuration with individual LED control capabilities
Integrates auto-breath function for dynamic lighting effects without MCU intervention
Utilizes I2C compatible interface for simplified programming and data transmission

Applications

LED dot matrix displays
Automotive intelligent signaling
Industrial control panels

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape-and-reel specifications. Check for RoHS compliance documentation and ensure the part number corresponds to the latest revision available from Lumissil Microsystems before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for medium-density LED matrices is required. The integrated auto-breath feature reduces microcontroller overhead compared to standard drivers. Ensure the application environment supports the specified operating temperature range and that the I2C bus timing aligns with the controller's capabilities for reliable communication.

Part Context

This part belongs to the IS31FL3736 series of LED lighting drivers designed for high-performance applications. It is distinct from the non-A variant and other series like the IS31FL3208A which offers different channel counts and topologies. The series focuses on providing efficient LED control with reduced external component count.

Replacement Considerations

The IS31FL3736-QFLS4-TR is listed as obsolete. Potential substitutes include the IS31FL3736A-QFLS4-TR if pin compatibility and functional equivalence are confirmed via datasheet comparison. No other public substitute part numbers are explicitly documented.
