IS31FL3751-QFLS4-TR

Overview

The IS31FL3751-QFLS4-TR is a general-purpose LED matrix driver manufactured by Lumissil Microsystems. It supports a 9x8 LED matrix configuration and is programmed via a 1MHz I2C compatible interface. The device features linear LED drivers with PWM dimming capabilities, delivering an output current of 31mA per channel. It operates within a supply voltage range of 2.7V to 5.5V and is housed in a compact 20-QFN (3mm x 3mm) package. This component is designed for applications requiring efficient LED control with minimal microcontroller overhead.

Feature Summary

Supports 9x8 LED matrix configuration
Programmed via 1MHz I2C compatible interface
Linear LED drivers with PWM dimming
Compact 20-QFN package

Applications

LED matrix displays
General purpose LED control systems
Battery-powered devices requiring low MCU overhead

Procurement Notes

Verify the specific suffix QFLS4-TR against the official Lumissil datasheet to confirm package type and tape-and-reel specifications. Ensure the design accommodates the 20-QFN (3mm x 3mm) footprint and thermal requirements. Confirm I2C bus compatibility at 1MHz speed with the host controller. Check for any recent Product Change Notifications (PCN) regarding manufacturing updates or material changes.

Selection Notes

Select this component when a fixed 9x8 matrix layout is required with simple I2C control. It is suitable for designs prioritizing low pin count and small board space due to the 3mm x 3mm QFN package. Consider the 31mA output current limit for LED brightness requirements. Verify that the 2.7V to 5.5V supply range matches the system power architecture.

Part Context

This part belongs to the IS31FL37xx series of LED display drivers from Lumissil Microsystems. These drivers are designed to reduce microcontroller overhead by handling LED scanning and dimming internally. The series typically offers various matrix sizes and interface options to suit different display density and control complexity needs.

Replacement Considerations

Check Lumissil documentation for direct pin-to-pin replacements within the IS31FL37xx family. Verify if alternative models offer compatible interfaces and current ratings. Ensure any substitute maintains the 20-QFN package dimensions for mechanical fit.
