Overview
The TLE4242GATMA1 is a linear LED driver IC manufactured by Infineon Technologies, designed for automotive lighting applications. It features a single output channel capable of delivering up to 500 mA of constant current. The device supports PWM dimming and operates within an input voltage range of 8 V to 16 V, with a maximum output voltage of 40 V. It is housed in a PG-TO263-7-1 package and complies with AEC-Q100 standards. The component functions effectively across a temperature range of -40°C to +150°C.
Feature Summary
- Linear topology providing stable constant current regulation for LED strings
- Integrated PWM dimming capability for precise brightness control
- Automotive-grade reliability certified under AEC-Q100 standards
Applications
- Automotive rear lighting systems
- Interior vehicle illumination
- Exterior automotive lighting fixtures
Procurement Notes
Verify the specific suffix ATMA1 to confirm the PG-TO263-7-1 package and tape-and-reel delivery format. Confirm AEC-Q100 qualification status for automotive integration requirements. Ensure compatibility with 8 V to 16 V supply rails during system design validation.
Selection Notes
Select this component for high-current linear LED driving where thermal management is feasible due to the TO-263 package. Compare against buck-boost alternatives if input voltage fluctuations exceed the linear regulator's dropout capabilities. Verify that the 500 mA output aligns with the target LED string configuration.
Part Context
This part belongs to the TLE4242 family of linear LED drivers from Infineon. It shares functional similarities with the TLE4242EJ but differs in package type and specific electrical characteristics. The family is targeted at robust automotive lighting solutions requiring simple external component counts.
Replacement Considerations
The TLE4242EJXUMA1 is listed as an alias or related variant in distributor databases. Verify pinout compatibility and thermal performance differences before substitution. Ensure the replacement matches the required PG-TO263-7-1 footprint.
