Completed the datasheet audit and saved the detailed findings in Part Datasheet Audit: LM5013QDDARQ1. The pin names/numbers and signal pad geometry largely match the TI datasheet, but I flagged incorrect metadata (Linear Regulator, TO package), missing pin types/descriptions, and a potentially undersized exposed-pad land pattern versus TI’s recommended thermal land.
Open items:
  • Datasheet URL was already set, so I did not change it; the official TI URL is https://www.ti.com/lit/ds/symlink/lm5013-q1.pdf.
  • Recommended cleanup: update part type/package metadata, populate pin descriptions/types, and review the EP pad thermal land.
Suggested next steps:
  1. Fix the metadata and pin properties from the audit.
  2. Adjust the exposed pad footprint if you want it to match TI’s example land pattern.
  3. Re-run a final part-quality check after edits.

Populate all pin types and descriptions from the datasheet.

flux

I’ll update each terminal’s Pin Type and Pin Description from the LM5013-Q1 datasheet, then verify the properties were applied.

flux

Pin properties are updated; I’m doing a final readback now to confirm every terminal matches the datasheet-derived mapping.

flux

Updated and verified all LM5013-Q1 terminal Pin Type and Pin Description properties from the datasheet.
Open items:
  • Used Open Collector for PGOOD because Flux has no separate Open Drain pin type option.
  • Used Passive for EP because the datasheet says the exposed pad has no internal electrical connection, though it should be tied to GND copper thermally.
Suggested next steps:
  1. Review/fix the exposed pad footprint size versus TI’s thermal land.
  2. Run a final part audit after footprint cleanup.
