IS32LT3175N-GRLA3-TR

Overview

The IS32LT3175N-GRLA3-TR is a single-channel linear LED driver IC designed for automotive applications. It delivers a fixed output current of 150mA with an input voltage range of 5V to 42V. The device features PWM dimming capability and includes fade-in/fade-out functionality with courtesy negative polarity input. Packaged in an 8-SOP-EP (8-SOIC with exposed pad) housing, it operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

Integrates internal power MOSFET for high-side linear regulation
Supports PWM dimming control for brightness adjustment
Includes built-in fade-in and fade-out timing functions
Features thermal shutdown protection for system reliability

Applications

Automotive exterior lighting systems
Interior ambient illumination circuits
LED signboard driving modules
General-purpose constant current LED sources

Procurement Notes

Verify the specific suffix 'N' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the 8-SOP-EP package footprint aligns with PCB layout guidelines. Confirm AEC-Q100 compliance documentation is available for automotive quality assurance processes before finalizing procurement.

Selection Notes

Select this component when a single-channel, high-voltage tolerant linear driver is required. The 150mA output current suits standard automotive LEDs. Consider the 42V supply range for direct battery connection scenarios. Evaluate the exposed pad package for thermal management needs in enclosed environments compared to standard SOIC packages without thermal pads.

Part Context

This part belongs to the IS32LT31xx family of high-side linear LED drivers from Lumissil Microsystems. These devices are engineered for robust performance in automotive environments, offering integrated protections and precise current regulation. The family supports various current options and dimming interfaces to accommodate diverse lighting architectures.
