Overview
The IS31FL3728-QFLS3-TR is an audio-modulated matrix LED driver manufactured by Lumissil Microsystems. It operates within a supply voltage range of 2.5V to 5.5V and supports I²C communication at frequencies up to 400kHz. The device features a maximum power consumption of 5mA and delivers an output current of 42.8mA per channel. It is housed in a QFN-24 package measuring 4.0mm x 4.0mm. The component functions reliably across an extended temperature range from -40°C to +105°C, ensuring stability in demanding environments.
Feature Summary
- Audio modulation capability for direct sound-to-light response without MCU intervention
- I²C interface for configuration and control with low power consumption
- High output current drive for matrix LED arrays
Applications
- Audio-reactive visual displays
- Matrix LED indicators
- Consumer electronics with sound synchronization
Procurement Notes
Verify the specific suffix QFLS3 against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the QFN-24 thermal pad soldering process aligns with the manufacturer's recommended reflow profile. Confirm that the operating temperature range meets your system's environmental specifications before finalizing procurement.
Selection Notes
Select this component when audio-driven LED patterns are required without complex microcontroller processing. The integrated audio modulation simplifies firmware development. Compare the 42.8mA output current against the total LED load requirements. Verify compatibility with the host system's I²C voltage levels and bus speed constraints.
Part Context
This part belongs to the IS31FL3728 series of LED display drivers designed for matrix applications. It integrates audio decoding logic directly into the driver circuitry. The series targets cost-sensitive applications requiring synchronized light and sound effects. It serves as a specialized solution for visual feedback in audio equipment.
Replacement Considerations
Check the IS31FL3728-QFLS2-TR variant for potential pin-compatible alternatives. Verify if the operating temperature range difference (-40°C to +85°C vs +105°C) impacts your application. Ensure any substitute maintains the same audio modulation functionality and I²C interface protocol.
