Part Metadata Audit and Update

Fixed the BQ25622RYKR symbol metadata to match the TI datasheet.
Changes made:
  • Renamed PMID_GDPG
  • Renamed ILIM/D-ILIM
  • Renamed TS_BIAS/D+TS_BIAS
  • Added datasheet-based pin descriptions for all 18 pins
  • Updated pin types using standard Flux values, including open-drain outputs as Open Collector, I²C SDA as Bi-Directional, and power pins as Power In / Power Out
I verified the final symbol: all 18 pin numbers, names, descriptions, and pin types are now aligned with the TI BQ25622 pin table.
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 parametric style, group pins into datasheet-based functional sections, and verify the section/order fields afterward.
Done. I set all 18 terminals to parametric-v1 and assigned datasheet-based sections, terminal order, and pin orientation.
Sections now used:
  • Power Supply: VBUS, PMID, BTST, SW, SYS, BAT, GND
  • Voltage Regulator: REGN, TS_BIAS
  • Control: ILIM, ~QON, PG, STAT, ~INT
  • Enable: ~CE
  • Analog: TS
  • Communication: SDA, SCL
Verified the updated symbol metadata after applying the changes.
