Overview
The TLD21421EPXUMA1 is a single-channel linear LED driver IC from Infineon’s LITIX™ family, housed in a PG-TSDSO-14 package. It operates within a supply voltage range of 5.5 V to 40 V and delivers an adjustable output current between 20 mA and 180 mA via external resistors. The device supports PWM dimming and includes integrated high-side switching. Key protection features include short-circuit detection, thermal shutdown, and open-load diagnosis. It functions without a microcontroller and meets automotive AEC-Q100 standards.
Feature Summary
- Single-channel linear current source with configurable output current
- Integrated PWM dimming capability for precise light control
- Comprehensive fault management including short-circuit and thermal protection
- Microcontroller-free operation using external resistor programming
Applications
- Automotive exterior lighting systems
- Interior ambient lighting modules
- Dashboard indicator illumination
- General-purpose LED string driving
Procurement Notes
Verify the specific suffix XUMA1 corresponds to the required reel packaging configuration. Confirm that the PG-TSDSO-14 package variant matches your PCB footprint requirements. Ensure compatibility with the intended supply voltage range of 5.5 V to 40 V for your specific application design.
Selection Notes
Select this component when a single-channel solution with up to 180 mA output is required. It is suitable for applications needing PWM dimming without complex digital interfaces. Consider alternative LITIX models if multiple channels or higher current capacities are necessary for the target design.
Part Context
This part belongs to the LITIX™ Basic+ family of linear LED drivers designed for automotive applications. It complements other devices like the TLD21313EPXUMA1 by offering a simplified single-channel architecture. The series emphasizes robust diagnostics and ease of integration into vehicle lighting networks.
Replacement Considerations
Direct substitutes may include other single-channel LITIX drivers such as the TLD11141EPXUMA1, though output current capabilities differ. Verify pinout compatibility and thermal performance before swapping components in existing designs.
