Part Datasheet Review and Validation

flux

Completed the part review and normalized the Datasheet URL to the official TI PDF: https://www.ti.com/lit/ds/symlink/drv8262-q1.pdf. I documented the detailed findings in DRV8262QDDWRQ1 Part Review (drv8262qddwrq1-part-review).
Open items flagged:
  • Description appears to overstate ratings: datasheet is 60 V operating, not 70 V operating; current is 16 A peak single / 8 A peak dual, not generic 20 A.
  • IPROPI and VREF dual-mode labels appear swapped versus the datasheet.
  • Pins 38/39 should include dual-mode aliases IN4/IN3.
  • Pin Type and Pin Description metadata are mostly missing/unspecified.
Suggested next steps:
  1. Rename the swapped IPROPI/VREF symbol terminals.
  2. Populate all Pin Type and Pin Description fields from the datasheet table.
  3. Update the part description to a datasheet-accurate headline rating.

Populate Pin Type and Pin Description fields for every terminal from the datasheet. and fix pin mismatches

flux

I’ll update every terminal’s Pin Type and Pin Description from the TI pin table, fix the swapped IPROPI/VREF names, add dual-mode aliases for pins 38/39, then re-read the schematic to verify.

flux

Completed. I populated Pin Type and Pin Description for all 45 terminals from the TI datasheet and fixed the symbol/footprint mismatches.
Open items:
  • None from this requested pass; verification confirmed the renamed terminals also propagated to footprint pad designators.
Suggested next steps:
  1. Run a final part validation/design review.
  2. Verify footprint geometry dimensions against TI DDW0044E land pattern if you want a deeper mechanical check.
