Overview
The TLD1124ELXUMA1 is a single-channel high-side LED driver from Infineon’s LITIX Basic family, designed for automotive lighting applications. It operates as a linear current source with an output current capability of 180 mA and supports PWM dimming. The device functions within an input voltage range of 5.5 V to 40 V, delivering up to 40 V output voltage. It features integrated short-circuit and thermal protection mechanisms. Packaged in a PG-SSOP-14 housing, it is qualified to AEC-Q100 standards for automotive reliability.
Feature Summary
- Single-channel high-side linear current source architecture
- Integrated PWM dimming control interface
- Automotive-grade qualification compliant with AEC-Q100
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- Tail lamp and brake light circuits
Procurement Notes
Verify the complete part number including the XUMA1 suffix to ensure correct tape-and-reel packaging configuration. Confirm that the PG-SSOP-14 package variant matches your PCB footprint requirements. Cross-reference the specific revision level against your design-in documentation to guarantee compatibility with existing firmware or hardware interfaces.
Selection Notes
Select this component when a single-channel, high-current linear driver is required for automotive environments. It is suitable for designs needing robust thermal protection and precise current regulation without complex external components. Consider alternative topologies if buck or boost conversion efficiency is critical rather than linear dissipation.
Part Context
This driver belongs to the LITIX Basic product family, which provides cost-effective solutions for basic LED control tasks. It complements higher-channel devices like the TLD7002 series by offering a simplified solution for single-point lighting applications requiring high reliability and standard automotive interface protocols.
Replacement Considerations
Direct substitutes include other single-channel LITIX drivers such as the TLD11141EPXUMA1, though topology differences (buck/boost vs. linear) must be evaluated. Verify pinout compatibility and current ratings before swapping with legacy Infineon parts.
