TLD11141EPXUMA1

Overview

The TLD11141EPXUMA1 is a single-channel linear LED driver from Infineon’s LITIX Basic+ family, designed for automotive applications. It operates within a supply voltage range of 5.5 V to 40 V and delivers an adjustable output current up to 360 mA per channel. The device features internal switching capabilities and supports PWM dimming control. It is housed in a PG-TSDSO-14 package with exposed pad for thermal efficiency. The component is qualified to AEC-Q100 standards and functions reliably across an extended junction temperature range of -40°C to +150°C.

Feature Summary

• Integrates advanced diagnosis and protection features including short circuit detection and thermal shutdown for robust operation.
• Supports flexible fault management with Single LED Short (SLS) diagnosis capability for enhanced system safety.
• Provides high output current accuracy suitable for precise automotive LED lighting control requirements.

Applications

• Automotive LED rear single light functions
• High-side linear LED current source applications
• Automotive exterior and interior lighting systems

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the PG-TSDSO-14 package variant matches your PCB footprint requirements. Ensure compliance with RoHS3 directives and check moisture sensitivity level (MSL 2A) handling procedures during assembly. Validate AEC-Q100 qualification status for your specific automotive grade requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring a single high-current linear LED channel with integrated diagnostics. It is suitable for boost, buck, or flyback topologies where linear regulation is preferred. Consider the 360 mA maximum output current and 40 V supply limit when sizing external components. The PG-TSDSO-14 package offers a compact solution with thermal performance benefits for space-constrained automotive boards.

Part Context
