Part Metadata Audit and Updates

flux

Fixed and verified.
Changes made:
  • Renamed pins:
    • PMID_GD → PG
    • 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.

flux

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.

Pin Description / Type Mismatches
  • All project terminal Pin Type properties are currently Unspecified; the datasheet provides specific types: P, AI, AIO, DI, DO, DIO. These should be populated for ERC/library quality.
  • Several terminal names appear inherited from another charger variant or combined-family symbol:
    • Pin 3 must be PG; current PMID_GD is incorrect.
    • Pin 4 should be D-; current ILIM/D- is ambiguous and not exact for BQ25620.
    • Pin 5 should be D+; current TS_BIAS/D+ is ambiguous and includes BQ25622-specific TS_BIAS naming.
  • Open-drain pins PG, STAT, INT require pull-ups in an application schematic; symbol terminal type should reflect open-drain output where possible.
  • CE must be tied high or low and not left floating in application designs.
Footprint Cross-Check
  • Layout contains 18 pad nodes corresponding to the 18 symbol terminals, so pad count matches the datasheet pin count.
  • The footprint asset is named for BQ25628RYKR, not BQ25620RYKR. This is a naming and traceability mismatch.
  • The datasheet package for BQ25620RYKR is RYK WQFN-HR, 2.5 mm x 3.0 mm, 18 pins. The current footprint should be verified against TI RYK0018A land pattern dimensions before release because the available asset name indicates it may have been imported/generated for a different family member.
  • The layout pad designators mirror the current symbol terminal names, so the same pin-name mismatches appear in the footprint pad labels.
Part Property Issues
  • Datasheet URL, MPN, manufacturer, designator prefix, and Part Type are present in library metadata.
  • Library metadata includes part-type-specific values logicFunction: AND and icType: Logic, which do not match this charger IC and should be corrected/removed if editable.
Summary of Required Fixes
  1. Rename symbol terminal pin 3 from PMID_GD to PG.
  2. Rename symbol terminal pin 4 from ILIM/D- to D-.
  3. Rename symbol terminal pin 5 from TS_BIAS/D+ to D+.
  4. Update terminal pin descriptions and pin types to match the datasheet table.
  5. Rename or replace the footprint asset so it is traceable to BQ25620RYKR / TI RYK0018A, and verify physical land pattern dimensions against the datasheet.
  6. Remove incorrect logic-family metadata (logicFunction: AND, icType: Logic) from the part if those fields are editable.
