IS31FL3752-QFLS4-TR

Overview

The IS31FL3752-QFLS4-TR is an LED display driver manufactured by Lumissil Microsystems, designed for matrix LED applications. It supports configurations of 8 RGB channels or 24 individual LEDs. The device operates within a supply voltage range of 2.7V to 5.5V and delivers an output current of 48mA per channel. It utilizes a linear topology with PWM dimming capabilities and communicates via a 1MHz I2C compatible interface. The component is housed in a 20-WFQFN package with an exposed pad, suitable for surface mount installation.

Feature Summary

Supports 8 RGB or 24-LED matrix configurations
Integrates 1MHz I2C compatible programming interface
Provides linear PWM dimming control
Operates across extended industrial temperature ranges

Applications

General purpose LED matrix displays
Compact battery-powered indicator systems
Automotive intelligent signaling displays

Procurement Notes

Verify the specific suffix QFLS4 against the latest manufacturer datasheet to confirm package dimensions and moisture sensitivity levels. Ensure the ordering quantity aligns with the factory reel packaging requirements specified by Lumissil Microsystems. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designing circuits requiring precise PWM dimming for small matrix arrays. The 48mA output current suits standard indicator LEDs. Verify that the host microcontroller supports the required I2C clock speed. Ensure the PCB layout accommodates the thermal requirements of the 20-WFQFN exposed pad package for adequate heat dissipation during continuous operation.

Part Context

This part belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems. These devices are engineered for high-density LED control in space-constrained environments. The series typically integrates constant current sinks with digital control interfaces, enabling simplified system architecture by reducing the processing load on the main controller.
