Specialized Procurement Notes

Verify the specific suffix codes against the official Infineon datasheet to ensure correct pinout and feature configuration. Confirm AEC-Q100 qualification status and operating temperature range requirements match the target application environment. Check for moisture sensitivity levels and recommended reflow soldering profiles during assembly planning.

Specialized Selection Notes

Select this component when a combined power switching and LIN communication solution is required for body electronics. Ensure the load current does not exceed the 400 mA continuous limit without considering thermal dissipation constraints. Verify compatibility with the system's LIN bus topology and baud rate requirements before finalizing the design.

Specialized Part Context

This part belongs to the TLE926x family of System Basis Chips, which are optimized for automotive body applications. It serves as a bridge between the microcontroller and peripheral loads, integrating power management and communication interfaces into a single compact package to reduce board space and component count.

Specialized Replacement Considerations

Consult Infineon documentation for direct replacements within the TLE926x series. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting with other SBC models from different manufacturers.
