Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the obsolete status and availability of suitable replacement parts such as the TLD1310ELXUMA1 prior to procurement. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling during assembly processes.
Selection Notes
Select this component for designs requiring three-channel high-side LED control with integrated power conversion. Consider the PG-SSOP-14-5 package constraints and thermal dissipation requirements. Evaluate the 120 mA output limit against specific LED load demands and verify compatibility with system voltage ranges between 5.5 V and 40 V.
Part Context
This IC belongs to Infineon's LITIX Basic series, specialized for automotive lighting applications. It simplifies design by combining driver and power stages in a single package. The TLD2326ELXUMA1 is designed to meet stringent automotive quality standards, offering robust performance in demanding electrical environments typical of vehicle lighting architectures.
Replacement Considerations
The TLD1310ELXUMA1 is listed as a parameter-equivalent alternative. Verify pinout compatibility and functional equivalence before substitution due to the original component's obsolete status.
