TI Part Audit

can you group together pins by their functions?
for example for Power, 3v3, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function.

flux

Yes. I’ll assign every physical pin to exactly one broad functional group based on its primary datasheet function, with no duplicates; Power and Ground will be separate, and Section will match Pin Group.

The metadata and pin grouping are updated. I’m doing a final read-back now, including the split-land pad mapping and the remaining legacy footprint-asset issue.

The part was reviewed against the official Texas Instruments BQ25628E datasheet (Rev. C). The Datasheet URL was set to: https://www.ti.com/l...

flux

Audited and corrected the part: official TI datasheet added, package set to RYK0018A WQFN-HR-18, all terminals verified, and pins grouped by primary function with matching Sections and no cross-group duplication.
The footprint geometry matches TI, but its imported asset retains incorrect legacy pad numbers 19–22 for split lands; I filed an internal quality report. Full findings: BQ25628ERYKR Part Audit.
