Part Metadata Audit and Updates

Fixed and verified.
Changes made:
  • Renamed pins:
    • PMID_GDPG
    • ILIM/D-D-
    • TS_BIAS/D+D+
  • Added TI datasheet-based pin descriptions for all 18 terminals.
  • Updated pin types using valid Flux ERC categories:
    • Power pins mapped to Power In, Power Out, or Ground
    • Open-drain outputs mapped to Open Collector
    • SDA/D+/D- mapped to Bi-Directional
    • Control pins mapped to Input
The terminal review checks now return no issues.
Please also create the parametric symbol and place each pin into the correct section based on the datasheet.
I’ll convert the symbol metadata to a parametric-style organization and assign each terminal to functional sections from the TI pin table, then verify the result.
Done. I set all 18 terminals to Symbol Style: Parametric and assigned datasheet-based sections:
  • Power: BTST, REGN, BAT, SYS, SW, PMID, VBUS
  • Ground: GND
  • Communication: D+, D-, SDA, SCL
  • Analog: TS
  • Control: PG, STAT, ~INT, ~CE, ~QON
I also added pin groups, orientations, and terminal order values, then verified the part review checks return no issues.
