TLD21413EPXUMA1

Overview

The TLD21413EPXUMA1 is a three-channel high-side LED driver IC from Infineon’s LITIX family, designed for automotive applications. It operates within an input voltage range of 5.5 V to 40 V and delivers up to 60 mA per channel. The device utilizes a boost topology to support output voltages up to 40 V. It features PWM dimming control and includes integrated short circuit and thermal protection mechanisms. The component is housed in a 14-TSSOP package with an exposed pad and is qualified to AEC-Q100 standards for operation between -40°C and +150°C.

Feature Summary

• Three-channel high-side configuration with independent current control
• Integrated boost topology for driving series-connected LEDs
• Supports pulse-width modulation (PWM) dimming functions
• Includes diagnostic features such as short circuit and thermal protection

Applications

• Automotive exterior lighting systems
• LED tail light modules
• Position lamp circuits
• High-side LED driver implementations in harsh environments

Procurement Notes

Verify the specific suffix XUMA1 indicates the reel packaging format when sourcing. Confirm that the AEC-Q100 qualification aligns with your automotive reliability requirements. Ensure the 14-TSSOP footprint matches your PCB design constraints. Check for any updated revision levels or alternate pin-compatible variants before finalizing procurement specifications.

Selection Notes

Select this component when a three-channel solution with integrated boost capability is required. It is suitable for applications needing precise current regulation up to 60 mA per channel. Consider its thermal performance and protection features for safety-critical automotive lighting. Compare against other LITIX variants if different channel counts or topologies are needed.

Part Context

This part belongs to the LITIX Basic+ family of linear current sources and sinks. It extends the functionality of standard drivers by adding advanced diagnosis and protection. The family targets highly efficient automotive LED lighting applications requiring flexible fault management and single LED short detection capabilities.

Replacement Considerations

Check for direct substitutes within the TLD21xxx series with matching channel counts and current ratings. Verify compatibility with existing boost inductor values and control signals. Ensure thermal dissipation characteristics remain adequate for the new component in the same enclosure.
