IS31FL3732-QFLS2-TR

Overview

The IS31FL3732-QFLS2-TR is an LED lighting driver IC designed for audio-modulated applications. It supports a 144-dot LED matrix configuration, utilizing 16 output channels to drive individual LEDs. The component operates within a supply voltage range of 2.7V to 5.5V and delivers up to 40mA per channel. It features I2C-compatible programming interfaces for control. The device is housed in a QFN-40 package measuring 5.0mm x 5.0mm, suitable for surface mount technology. It includes humidity sensitivity classification and is supplied in tape and reel packaging.

Feature Summary

Supports audio modulation for dynamic LED driving applications
Configurable 144-dot LED matrix via 16 independent output channels
I2C compatible interface for digital programming and control

Applications

Audio-reactive LED visualizers
Matrix LED display systems
Compact LED lighting drivers

Procurement Notes

Verify the NRND (Not Recommended for New Designs) status before integration into new products. Confirm the QFN-40 package dimensions and moisture sensitivity level requirements during PCB layout. Ensure the I2C bus timing aligns with the datasheet specifications for reliable communication. Check for available replacement components due to potential end-of-life constraints.

Selection Notes

Select this component for designs requiring direct audio input modulation without complex MCU processing. The 16-channel output is sufficient for small matrix displays. Verify that the 40mA current capability meets the specific LED forward current requirements. Consider the thermal performance of the QFN-40 package under continuous operation conditions.
