Overview
The TLD1125ELXUMA1 is a single-channel linear LED driver IC from Infineon’s LITIX family, designed for automotive lighting applications. It operates within an input voltage range of 5.5 V to 40 V and delivers a constant output current of up to 360 mA. The device supports PWM dimming control and features adjustable output voltage capabilities. It is housed in a PG-SSOP-14-EP package and is qualified to AEC-Q100 standards, ensuring reliability across an operating temperature range of -40°C to +150°C.
Feature Summary
- Integrates linear regulation with PWM dimming capability for precise LED current control
- Includes built-in short circuit and thermal protection mechanisms for enhanced system safety
- Supports flexible topology configurations including boost, buck, and flyback arrangements
Applications
- Automotive exterior lighting systems
- Interior ambient lighting modules
- High-side LED driver circuits requiring linear regulation
Procurement Notes
Verify the complete ordering part number, including suffixes, against official Infineon documentation to ensure correct package type and tape/reel specifications. Confirm that the specific variant matches your design requirements for voltage range and current settings. Cross-reference datasheet revisions to ensure compatibility with existing manufacturing processes and quality standards.
Selection Notes
Select this component when a single-channel, high-voltage tolerant linear driver is required for automotive LED applications. It is suitable for designs needing integrated protection features and PWM dimming without external complex circuitry. Ensure the thermal management strategy accounts for the linear regulation dissipation characteristics under maximum load conditions.
Part Context
This part belongs to Infineon’s LITIX series of intelligent power switches and drivers, specifically tailored for automotive lighting. The TLD1125ELXUMA1 complements other channel variants like the TLD2314ELXUMA1 by offering a single-channel solution with similar robust protection features and AEC-Q100 qualification for harsh automotive environments.
Replacement Considerations
Check for direct pin-to-pin compatible alternatives within the same LITIX family or comparable single-channel linear drivers from other manufacturers. Verify that any substitute maintains the same voltage tolerance, current rating, and protection feature set to ensure seamless integration into existing automotive lighting designs.
