IS31FL3216A-QFLS3-TR

Overview

The IS31FL3216A-QFLS3-TR is a 16-channel LED driver IC from Lumissil Microsystems, designed for dynamic lighting effects and animation control. It features an internal 80C51 core with RAM to store eight frames of data for small animations. The device supports linear PWM dimming with an output current of 21 mA per channel. It operates on a supply voltage range of 2.7 V to 5.5 V and utilizes an I2C interface for control. The component is housed in a QFN-28 package (4mm x 4mm) and functions within a temperature range of -40°C to +105°C.

Feature Summary

Supports audio modulation mode for dynamic lighting synchronization
Integrates internal RAM capable of storing eight frames for animation playback
Provides independent linear PWM dimming control across sixteen channels

Applications

Dynamic LED lighting effects and animation control
Audio-modulated visual displays
Compact battery-powered smart lighting devices

Procurement Notes

Verify the specific suffix 'QFLS3-TR' against the manufacturer's official documentation to confirm tape-and-reel packaging and automotive-grade qualification status. Ensure the target application environment remains within the specified operating temperature limits and voltage constraints defined in the datasheet. Cross-reference the I2C address settings to prevent bus conflicts in multi-device systems.

Selection Notes

Select this component when designing systems requiring integrated animation storage and audio-reactive LED driving without external microcontroller overhead. The QFN-28 package suits space-constrained layouts. Confirm that the required number of channels aligns with the sixteen available outputs and that the I2C communication protocol matches the host controller capabilities.
