Overview
The IS31FL3731-SALS2-TR is an LED driver IC featuring 18 linear constant current outputs. It supports analog dimming with a maximum output current of 34mA per channel. The device operates on a supply voltage ranging from 2.7V to 5.5V and functions within a temperature range of -40°C to +85°C. It is housed in a 28-pin SSOP package.
Feature Summary
- Provides 18 independent linear constant current channels for LED control
- Supports analog dimming functionality for brightness adjustment
- Operates within a wide supply voltage range of 2.7V to 5.5V
Applications
- LED matrix displays
- Segmented LED indicators
- General LED lighting applications
Procurement Notes
Verify the specific suffix SALS2-TR against official Lumissil documentation to confirm the SSOP package type and tape-and-reel packaging configuration. Ensure compatibility with system voltage requirements between 2.7V and 5.5V. Confirm that analog dimming meets the design specifications, as PWM capabilities are not listed for this variant.
Selection Notes
Select this component when 18 linear channels are required with analog dimming control. The SSOP package suits designs where surface mount space allows for wider pitch compared to QFN options. Verify thermal management needs for linear regulation at 34mA per channel across the operating temperature range.
Part Context
This part belongs to the IS31FL3731 family of LED drivers from Lumissil Microsystems. It shares core functionality with variants like the QFLS2-TR but differs in package style (SSOP vs. QFN) and potentially pinout or mechanical dimensions. It serves as a dedicated solution for driving multiple LEDs without complex microcontroller overhead.
Replacement Considerations
The IS31FL3731-QFLS2-TR is a related variant within the same product family. Substitution requires verification of package footprint differences between SSOP and QFN types and confirmation that electrical characteristics remain identical for the specific application.
