Part Metadata Audit and Update

flux

Done. I set datasheet-based pin types, sections, terminal order, and short pin descriptions for all 37 BQ25750RRVR terminals, and converted the symbol terminals to parametric-v1.
I also corrected the two naming issues from the audit: FSW__SYNC → FSW_SYNC, and pin 37 GND → THERMAL_PAD with Ground pin type and “Exposed thermal pad” description.

Can you make the sections shorter or use fewer sections?

flux

I’ll consolidate the custom section names into a smaller set of standard, shorter sections while preserving the pin types and descriptions.

flux

Done. I reduced the BQ25750RRVR symbol from many long functional sections down to 8 shorter groups:
  • Interface
  • Control
  • Analog
  • Sense
  • Battery
  • Gate Drive
  • Adapter
  • Power
Pin types, terminal order, pin numbers, and descriptions were preserved.
