IS31FL3716-QFLS4-TR

Overview

The IS31FL3716-QFLS4-TR is a linear LED matrix driver manufactured by Lumissil Microsystems, designed for general-purpose applications. It supports configurable matrix layouts including 8x7, 9x6, and 10x5 configurations. The device operates within a supply voltage range of 2.7V to 5.5V and delivers an output current of approximately 40mA per channel. It features I²C-compatible programming interfaces for dimming control and utilizes a 20-pin QFN package measuring 3mm x 3mm.

Feature Summary

• Supports flexible matrix configurations such as 8x7, 9x6, and 10x5 LED arrangements
• Integrates I²C compatible interface for digital control and dimming
• Utilizes linear topology with no internal switches for simplified design

Applications

• General purpose LED matrix displays
• Compact indicator lighting systems
• Battery-powered devices requiring low power consumption

Procurement Notes

Verify the specific suffix -QFLS4-TR against the manufacturer's latest datasheet to confirm pinout compatibility and packaging specifications. Ensure that the I²C address settings align with your system architecture before integration. Cross-reference the operating temperature range with your environmental requirements to guarantee reliable performance under all expected conditions.

Selection Notes

Select this component when a small form factor is required due to its compact 3mm x 3mm footprint. It is suitable for designs needing multiple independent LED channels controlled via a standard two-wire interface. Consider the linear regulation characteristics and maximum output current limits when designing thermal management solutions for high-density LED arrays.

Part Context

This part belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems, which focuses on integrated solutions for display and signaling applications. The series is characterized by its ability to drive complex LED matrices using minimal external components. This specific model targets cost-sensitive and space-constrained markets where efficient control of multiple LEDs is necessary without complex multiplexing hardware.

Replacement Considerations

Check for direct substitutes within the IS31FL37xx family that offer similar pin counts and electrical characteristics. Verify compatibility with existing PCB footprints and firmware libraries if migrating from previous versions or alternative manufacturers.
