IS31FL3099-QFLS4-TR

Overview

The IS31FL3099-QFLS4-TR is a linear LED driver IC manufactured by Lumissil Microsystems, designed for lighting applications. It features 9 output channels with a maximum current of 40mA per channel. The device operates on an I2C interface for control and supports multi-step and PWM dimming methods. It functions within a supply voltage range of 2.7V to 5.5V and withstands operating temperatures from -40°C to +125°C. The component is housed in a compact 20-pin QFN package measuring 3.0mm x 3.0mm.

Feature Summary

Integrates a 9-channel linear shift register for direct LED control
Supports I2C communication for digital configuration and data transfer
Enables precise brightness adjustment through combined multi-step and PWM dimming techniques

Applications

General LED lighting systems requiring compact form factors
Backlighting solutions for displays and indicators
Automotive interior lighting modules

Procurement Notes

Verify the specific suffix QFLS4 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with I2C bus voltage levels and check for any recent Product Change Notifications (PCN) regarding lead frame suppliers or assembly sources that may affect long-term availability or physical dimensions.

Selection Notes

Select this component when a low-profile solution is required for driving multiple LEDs with independent control. The linear topology suits applications where efficiency is secondary to cost and simplicity. Verify that the 40mA output capability meets the forward current requirements of the target LEDs without exceeding thermal limits within the specified 3.0mm x 3.0mm footprint constraints.

Part Context

This part belongs to the IS31FL3x series of industrial-grade LED drivers from Lumissil Microsystems. These components are engineered for wide-range LED support and include EMI noise reduction technologies. The IS31FL3099 specifically targets applications needing fewer channels than larger variants like the IS31FL3209, offering a balance between channel count and package size.
