TLD1121ELXUMA1

Overview

The TLD1121ELXUMA1 is a three-segment LED driver IC from Infineon Technologies, designed for automotive applications. It features a linear dimming architecture with a maximum output current of 360 mA per channel. The device operates within an input voltage range of 5.5 V to 40 V and supports PWM control for precise brightness adjustment. It is housed in a PG-SSOP-14-EP package and complies with AEC-Q100 standards, ensuring reliability in harsh environments.

Feature Summary

• Supports three independent LED segments with linear dimming capability
• Integrated PWM control interface for accurate brightness regulation
• Automotive-grade qualification compliant with AEC-Q100 standards
• Robust protection mechanisms including short circuit and thermal shutdown

Applications

• Automotive exterior lighting systems
• Interior vehicle illumination modules
• Dashboard and instrument cluster backlighting
• Signaling and indicator light circuits

Procurement Notes

Verify the specific suffix ELXUMA1 to confirm tape-and-reel packaging and automotive grade status. Ensure compatibility with existing PCB footprints for the PG-SSOP-14-EP package. Confirm that the design accounts for the linear topology's thermal dissipation requirements under maximum load conditions. Check for any obsolescence notices as this component may be subject to lifecycle changes.

Selection Notes

Select this component when a multi-channel solution is required for automotive LED arrays. The linear topology suits applications where cost-effective simplicity is prioritized over high-efficiency switching. Ensure the system voltage remains within the 5.5 V to 40 V operational window. Consider thermal management strategies due to the inherent losses in linear regulation at higher currents or voltage differentials.

Part Context

This part belongs to Infineon's TLD series of LED drivers, specifically tailored for automotive lighting. It integrates multiple channels into a single compact package, reducing board space compared to discrete solutions. The inclusion of EP (Exposed Pad) enhances thermal performance by facilitating heat dissipation through the substrate.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternatives based on pin compatibility, current rating, and package dimensions. Verify that any replacement maintains AEC-Q100 compliance and similar protection features for automotive safety.
