IS31FL3739-GRLS4-TR

Overview

The IS31FL3739-GRLS4-TR is a linear LED driver IC manufactured by Lumissil Microsystems, housed in a 24-pin SOP package. It features an I2C bus compatible interface operating at up to 1MHz for programming. The device supports general-purpose applications with an 8x8 or 7x9 matrix configuration. It provides PWM dimming capabilities and delivers a maximum output current of 35mA per channel.

Feature Summary

Supports 8x8 or 7x9 matrix LED configurations
Features a 1MHz I2C bus compatible interface
Provides linear LED driving with PWM dimming

Applications

General-purpose LED matrix displays
Dot matrix signage
Consumer electronic indicators

Procurement Notes

Verify the specific suffix GRLS4 against official Lumissil documentation to confirm pinout and thermal characteristics. Ensure the 24-SOP package matches the target PCB footprint. Confirm that the 35mA output rating aligns with the connected LED forward current requirements. Validate the I2C address settings for system integration.

Selection Notes

Select this component for designs requiring a compact solution for small LED matrices. The integrated PWM controller reduces microcontroller overhead. Consider the 35mA limit when determining LED brightness levels. The I2C interface simplifies control wiring compared to parallel data lines.

Part Context

This part belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems. These devices are designed for efficient control of LED arrays using minimal external components. The series offers various package options and channel counts to suit different display densities.

Replacement Considerations

Cross-reference with IS31FL3731-QFLS2-TR or IS31FL3731-SALS2 for similar segment driver functionality. Verify compatibility regarding package type and interface speed before substitution.
