Part Review and Datasheet Verification


Completed the L9961TR part review and saved the detailed findings in l9961tr-part-review.
Key flags: the Datasheet URL was already set to ST’s official PDF, but the project properties show incorrect Part Type: Inductors and Package or Case Code: TO; official package is VFQFPN 5x5x1 32L P0.5. The main pinout mismatches are pin 13 and pin 27, which the ST-sourced pin table lists as GND while the symbol currently uses TM_ENTER and TM1.
Suggested next steps:
  • Correct the package and part-type properties.
  • Verify pins 13/27 directly in the PDF before editing the symbol.
  • Populate Pin Type and Pin Description properties from the datasheet.
  • Verify exact QFN exposed-pad and perimeter-pad geometry before fabrication.
Populate Pin Type and Pin Description properties from the datasheet.
I’ll update each terminal’s Pin Type and Pin Description from the ST L9961 datasheet pin table, then re-read the schematic to verify the properties landed correctly.
The first pass added the datasheet detail, but Flux warned that several Pin Type values were non-standard; I’m normalizing them to Flux’s supported Pin Type options while keeping the detailed electrical behavior in Pin Description.
Populated Pin Type and Pin Description for all 33 terminals and verified the updates in the schematic.
I normalized Pin Type values to Flux-supported options while preserving datasheet-specific details like analog input, open-drain, active level, and pull-down behavior in Pin Description. Pins 13 and 27 are now treated as GND terminals based on the ST pin table.
