Procurement Notes
Verify the complete part number including suffixes against official Infineon documentation to ensure correct package and temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Cross-reference datasheet revisions to validate pinout and electrical characteristics match your design requirements.
Selection Notes
Select this component for applications requiring three independent LED channels with integrated diagnostics. It is suitable for designs needing high current accuracy and protection against common faults like shorts and opens. Ensure the system voltage remains within the 4.5 V to 36 V operating range and that thermal management aligns with the PG-TFDSO-16 package constraints.
Part Context
This device belongs to the LITIX Basic+ family, which extends the standard LITIX line with enhanced diagnosis features. It complements other linear current sources in the portfolio, offering a balance of performance and cost for mid-range automotive lighting applications where detailed fault reporting is required.
Replacement Considerations
Consult Infineon's official cross-reference tools for verified substitutes. No specific public substitute part numbers are confirmed in the provided data.
