IS31FL3726A-SALS4-TR

Overview

The IS31FL3726A-SALS4-TR is a 16-channel LED driver IC manufactured by Lumissil Microsystems. It features a 30MHz serial interface and is housed in a 24-pin SSOP package measuring 5.30mm in width. The device provides an output current of 25.2mA per channel without dimming capabilities.

Feature Summary

• Supports 16 independent LED channels for linear shift register control
• Utilizes a high-speed 30MHz serial communication interface
• Delivers constant current output at 25.2mA per channel

Applications

• LED lighting driver systems
• Matrix LED display modules
• General-purpose LED signaling applications

Procurement Notes

Verify the specific suffix SALS4 to confirm the SSOP package variant, as other packages like QFN exist within the same product family. Ensure the design supports the 30MHz serial interface timing requirements. Confirm that the 25.2mA output current aligns with the target LED forward current specifications. Check for any recent Product Change Notifications regarding manufacturing updates.

Selection Notes

Select this component when a 16-channel solution with a serial interface is required. The SSOP package offers a specific footprint alternative to the QFN version. Consider the fixed 25.2mA output current for LED brightness requirements. This part lacks internal dimming functions, requiring external control if variable intensity is needed.

Part Context

This component belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems. The series includes variants with different channel counts and package types. The IS31FL3726A specifically targets applications needing multiple channels controlled via a serial bus rather than parallel inputs.

Replacement Considerations

The IS31FL3726A-QFLS4-TR serves as a direct functional substitute but utilizes a QFN-24 (4.0mm x 4.0mm) package instead of the SSOP-24. Verify PCB layout compatibility before substitution due to the package difference.
