Part Review and Datasheet Update


Reviewed the NPM1100-QDAA-R7 part metadata, symbol pins, and footprint against Nordic’s nPM1100 documentation. I recorded the official Nordic datasheet URL in project metadata and created the detailed review here: part-review-npm1100-qdaa-r7.
Open items / mismatches:
  • Pin 3 is labeled VOUTBSET2; latest Nordic docs say it should be VOUTBSET0.
  • Pin 4 is labeled NC_1; latest Nordic docs say it should be AVSS ground.
  • Exposed pad is labeled GND; datasheet names it AVSS — electrically OK, but naming should be clarified.
  • Pin types/descriptions are mostly unspecified and should be populated from the datasheet.
Suggested next steps:
  1. Rename/fix the mismatched terminals.
  2. Populate pin descriptions and pin types from the datasheet.
  3. Re-check the footprint pad geometry against the QFN-24 4×4 mm exposed-pad land pattern.
Fix the pin mismatches, populate pin descriptions, and pin type then run a symbol/footprint review.
I’ll correct the mismatched NPM1100-QDAA-R7 pins, populate pin descriptions/types from the Nordic QFN24 pin table, then run a fresh schematic/footprint review.
I found the three symbol naming mismatches still present: pin 3, pin 4, and the exposed pad label. I’m applying the corrected Nordic QFN24 names and descriptions now.
Updated the symbol/footprint pin labels and metadata: VOUTBSET2 → VOUTBSET0, NC_1 → AVSS, and exposed pad GND → AVSS_EP. I populated all 25 terminals with datasheet-based pin descriptions and Flux-valid pin types, then reviewed the symbol/footprint checks; no open warnings/errors were reported.
Open items:
  • The exposed pad is named AVSS_EP to avoid duplicate AVSS labels while preserving datasheet meaning.
  • Pad geometry dimensions were not exposed in the review output, so only pad naming/count consistency was verified.
Suggested next steps:
  1. If desired, import/check the exact Nordic QFN-24 4×4 mm land pattern dimensions.
  2. Publish the corrected part revision.
