Part Validation and Datasheet Update

flux

Completed the LM74930QRGERQ1 part review and saved the detailed results in lm74930qrgerq1-part-validation-review. The pinout and 25-pad footprint count match the TI datasheet; flagged issues are missing pin descriptions, all pin types set to Unspecified, and the Datasheet URL using an uploaded PDF instead of the official TI URL.
Open items:
  • Exact footprint dimensions weren’t verifiable from the available layout inspection output.
  • Datasheet URL property is populated, so I did not overwrite it.
Suggested next steps:
  1. Update the Datasheet URL to https://www.ti.com/lit/ds/symlink/lm74930-q1.pdf.
  2. Add datasheet-based pin descriptions.
  3. Assign proper electrical pin types for better ERC behavior.

Update the Datasheet URL, add pin descriptions, assign pin types, and run a final ERC-style review.

I’ll update the datasheet URL and terminal metadata from the TI datasheet, then run a final schematic review for remaining issues.

flux

Updated the Datasheet URL to the official TI PDF, added datasheet-based descriptions to all 25 terminals, and assigned ERC-friendly pin types including power, ground, output, input, passive, not-connected, and open-collector fault output.
Open items:
  • The ERC/check query returned no matching ERC or component-review issues, so there are no flagged violations from the available review set.
  • Exact footprint geometry was not re-verified here; only the existing 25-pad structure had been previously confirmed.
Suggested next steps:
  1. Verify the RGE 24-VQFN pad geometry against TI’s mechanical drawing.
  2. Publish/update the part once the footprint geometry is confirmed.
