IS32LT3174-GRLA3-TR

Overview

The IS32LT3174-GRLA3-TR is a single-channel linear LED driver IC manufactured by Lumissil Microsystems. It provides a constant output current of 200mA and supports linear dimming with fade-in/fade-out functionality. The device operates within a supply voltage range of 6V to 45V and features an internal switch. It is housed in an 8-SOP-EP package (8-SOIC, 3.90mm width) with an exposed pad for thermal management. The component is AEC-Q100 qualified for automotive applications and functions across a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-side linear driver with internal power MOSFET for compact design
Supports analog linear dimming with controlled fade-in and fade-out transitions
Includes built-in protection mechanisms for extended operational life
Qualified for automotive environments under AEC-Q100 standards

Applications

Automotive exterior lighting systems
General commercial LED illumination
Residential smart lighting fixtures

Procurement Notes

Verify the current manufacturing status before procurement as this part number has been marked as obsolete or discontinued by the manufacturer. Check for Product Change Notifications (PCN) regarding end-of-life timelines. Confirm that alternative sources are authorized distributors to ensure component authenticity and traceability. Evaluate replacement options if long-term supply stability is required for production.

Selection Notes

Select this component for designs requiring simple linear control of single-channel LEDs without complex digital interfaces. Ensure the input voltage remains within the 6V to 45V operating range. Consider the thermal performance of the 8-SOP-EP package for heat dissipation requirements. Verify compatibility with the target application's dimming speed needs due to the analog fade characteristics.

Part Context

This device belongs to the Lumissil IS32LT31xx family of high-side linear LED drivers. These components are designed for general lighting applications using monolithic integrated solutions. The family emphasizes flexibility in design and reliability through integrated protections, targeting markets such as automotive, industrial, and consumer electronics where robust LED driving is essential.
