Overview
The TLD23623ETXUMA1 is a three-channel low-side driver IC from Infineon's LITIX Basic+ family, designed for automotive LED applications. It features integrated linear output stages capable of delivering up to 150 mA per channel with thermal derating and fault management. The device supports PWM dimming and operates within a supply voltage range of 4.5 V to 36 V. It is housed in a PG-TFDSO-16 package and is qualified under AEC-Q100 standards for automotive reliability.
Feature Summary
- Three-channel low-side driver architecture with integrated linear output stages
- Supports PWM dimming for precise LED brightness control
- Includes thermal derating and comprehensive fault management mechanisms
Applications
- Automotive exterior lighting systems
- Interior ambient LED illumination
- General-purpose low-side switching in automotive environments
Procurement Notes
Verify the complete part number including the suffix ETXUMA1 to ensure correct packaging and tape-and-reel configuration. Confirm that the application environment meets the specified operating temperature and voltage ranges defined in the official datasheet. Ensure compatibility with the PG-TFDSO-16 footprint during PCB layout design.
Selection Notes
Select this component when a three-channel solution with integrated linear regulation and fault protection is required. It is suitable for designs needing AEC-Q100 qualification and PWM dimming capabilities. Consider the 150 mA per channel limit and the 36 V maximum supply voltage when sizing the load.
Part Context
This device belongs to the LITIX Basic+ series, which provides robust low-side driving solutions for automotive LED applications. The series emphasizes reliability and integrated protection features, making it suitable for critical lighting functions where fault detection and thermal management are essential for system safety.
Replacement Considerations
Check for direct pin-to-pin replacements within the same LITIX family or other Infineon low-side drivers with similar channel counts and current ratings. Verify that any substitute maintains the same package type and electrical characteristics.
