Part Audit Report Scope
Audit of project metadata, schematic symbol terminals, and PCB footprint against Texas Instruments BQ7961x-Q1 datasheet Rev. F (June 2026) and PAP0064F package information.
Authoritative references
The project already has a Datasheet URL populated, so it was not overwritten. The attached PDF identifies itself as the official TI datasheet, Rev. F.
Current metadata Datasheet key specifications
  • 16-series-cell automotive precision battery monitor, balancer, and integrated hardware protector.
  • Supports 6S to 16S operation for BQ79616-Q1.
  • Total module operating voltage: 9 V to 80 V; 11 V to 80 V for OTP programming.
Audit complete. The existing datasheet is official TI content, so it was not replaced; critical issues include an invalid/questionable MPN, incorrect TO package metadata, numeric-only untyped symbol pins, and an oversized exposed pad.
Full specifications, 65-pad mapping, and footprint comparison are in Part Audit Report. I also filed an internal part-quality report for review.
Fix the metadata, terminal names/types/descriptions, and exposed-pad footprint per the TI datasheet.
I’ll apply the TI-backed metadata, fully define all 65 terminals, correct the PowerPAD geometry, then re-inspect the symbol and footprint against PAP0064F.
Metadata and all terminals are updated; I’m doing the final readback of pin mapping, rendered symbol, and the corrected 6.5 × 8.0 mm PowerPAD.
Updated the part to TI’s BQ79616PAPRQ1 data: official datasheet, PAP0064F package metadata, and all 65 terminals now have correct names, electrical types, descriptions, grouping, and pin numbers. The centered PowerPAD is corrected to 6.5 × 8.0 mm, with reduced paste coverage.
  • Open item: Paste is a reduced single 3.5 × 5.0 mm aperture; segmented stencil apertures require rebuilding/augmenting the footprint geometry.
  • Verification confirms 65 unique terminals, 65 mapped pads, and no reported part-review findings.
