It features integrated and protected output stages with a power shift capability to manage load transients. The device operates within an ambient temperature range of -40°C to +150°C and holds AEC-Q100 qualification. It utilizes a 16-TFSOP surface-mount package, ensuring robust performance in demanding automotive environments while providing precise current regulation for connected LED loads.

Feature Summary

• Three-channel low-side driver architecture with integrated protected output stages
• Power shift feature for managing dynamic load conditions
• Automotive-grade reliability with AEC-Q100 qualification
• Extended operating temperature range suitable for harsh environments

Applications

• Automotive exterior lighting systems
• Interior LED illumination control
• High-brightness LED driving circuits
• General-purpose low-side switching in automotive ECUs

Procurement Notes

Verify the specific suffix ETXUMA1 against the official Infineon datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 16-TFSOP case. Confirm that the design supports the required thermal dissipation for the intended application environment. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a three-channel low-side solution with integrated protection is required for automotive LED applications. Consider the power shift feature if the design involves significant load transients or inductive kickback scenarios. Evaluate the 16-TFSOP package constraints against available board space. Verify that the AEC-Q100 grade meets the specific vehicle manufacturer's quality standards.

Part Context

This part belongs to the TLD23xx series of low-side drivers from Infineon, which are optimized for automotive lighting. These ICs typically integrate diagnostic features and protection mechanisms such as overcurrent and thermal shutdown. The series is designed to replace discrete solutions, reducing component count and improving system reliability in modern vehicle electronics architectures.

Replacement Considerations

Check for direct pin-to-pin replacements within the TLD23xx family, such as the TLD23723ETXUMA1, if channel count or specific protection features differ. Verify that any substitute maintains the same AEC-Q100 qualification and thermal characteristics.
