Procurement Notes

Verify the specific ordering suffix matches the required voltage regulator output and packaging configuration. Confirm AEC-Q100 qualification status is required for the target automotive application. Ensure the 32-TSSOP exposed pad footprint aligns with the PCB design guidelines provided in the official datasheet. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity.

Selection Notes

Select this component when a dedicated LIN core SBC is needed to simplify ECU design by integrating power and communication functions. Consider the 4.5V to 28V input range for standard automotive electrical environments. The 32-TSSOP package offers a surface-mount solution suitable for space-constrained boards. Verify that the LIN interface speed and peripheral requirements match the system architecture before finalizing the selection.
