IS31FL3207-QFLS4-TR

Overview

The IS31FL3207-QFLS4-TR is an 18-channel LED driver IC from Lumissil Microsystems, housed in a QFN-28 package measuring 4.0mm x 4.0mm. It operates on a supply voltage range of 2.7 V to 5.5 V with a maximum power consumption of 10 mA. The device supports selectable PWM frequency and delivers constant current outputs up to 38 mA per channel. Designed for automotive reliability, it functions within a temperature range of -40°C to +125°C.

Feature Summary

Supports selectable PWM frequency for flexible dimming control
Provides 18 independent constant current output channels
Integrated short circuit and thermal protection mechanisms

Applications

Automotive interior lighting systems
Dashboard illumination arrays
Ambient cabin lighting modules

Procurement Notes

Verify the specific suffix QFLS4-TR confirms the reel tape packaging format and automotive-grade qualification status. Ensure the design accommodates the QFN-28 thermal pad requirements for optimal heat dissipation at high ambient temperatures. Confirm I2C address configurations match the system bus topology before finalizing the bill of materials.

Selection Notes

Select this component when an 18-channel solution with adjustable PWM timing is required. It is suitable for designs needing operation across the full automotive temperature spectrum. Consider alternative models if higher output current or different interface protocols are necessary.

Part Context

This part belongs to the IS31FL32xx series of LED drivers designed for automotive applications. It shares the QFN-28 footprint with related variants but differs in control interfaces and current capabilities. The series targets complex lighting architectures requiring precise channel management.

Replacement Considerations

Direct substitutes include IS31FL3209-QFLS4-TR for I2C-controlled applications and IS31FL3238-QFLS4-TR for PWM-only dimming. Verify pin compatibility and current ratings before swapping.
