IS31FL3731-SALS2

Overview

The IS31FL3731-SALS2 is a linear LED driver IC manufactured by Lumissil Microsystems. It features 18 output channels with analog dimming capability and a maximum current of 34mA per channel. The device operates within a supply voltage range of 2.7V to 5.5V and supports an operating temperature range from -40°C to +85°C. It is housed in a 28-SSOP package.

Feature Summary

Provides 18 independent output channels for LED matrix driving
Supports analog dimming control for brightness adjustment
Linear regulation topology for simplified circuit design

Applications

LED matrix displays
Automotive interior lighting
Consumer electronics backlighting

Procurement Notes

Verify the specific suffix SALS2 against official Lumissil documentation to confirm the SSOP package type and tape-and-reel orientation. Ensure the selected variant matches the required thermal performance and pinout configuration for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when an 18-channel solution with analog dimming is required. Compare against the QFLS2 variant if a QFN package or different automotive qualification level is needed. Verify that the 34mA output current meets the specific LED forward current requirements of the application design.

Part Context

This part belongs to the IS31FL3731 family of LED matrix drivers from Lumissil Microsystems. The family includes variants with different packages, such as the QFLS2 in a 28-QFN format. These devices are designed for applications requiring multiple synchronized LED outputs with precise current control.

Replacement Considerations

The IS31FL3731-QFLS2-TR is a documented alternative within the same product family, offering identical electrical functionality but packaged in a 28-QFN format instead of the 28-SSOP used by the SALS2 variant.
