Part Verification Report

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

flux

I’ll inspect the part metadata, symbol, footprint, and pins; locate the official TI datasheet if needed; update the Datasheet property; then report verified specs and any mismatches.

Review complete. The official TI datasheet was already linked, and the 8-pin symbol mapping is correct; however, the footprint pads are shorter than TI’s recommended land pattern, package/type metadata is incorrect, and pin types/descriptions are missing. Full findings are in the Part Verification Report; I also filed an internal part-quality report.

Symbol Issues
  • Every terminal currently has Pin Type = Unspecified instead of Analog, Power, or Ground.
  • Terminal Pin Description properties are absent. The pin names are correct, but the symbol does not include the functional descriptions and usage constraints from the datasheet.
  • Pin 7 is correctly named SS for TPS62933DRLR. It must not be confused with the pin-compatible TPS62933P/O variants, where pin 7 is PG.
Footprint Cross-Check
Correct items
  • Eight pads are present.
  • Pad numbering and physical sequence agree with the datasheet top-view pinout.
  • Pad pitch is 0.5 mm.
  • The fabricated body outline is approximately 1.2 mm × 2.1 mm, consistent with the DRL package nominal size.
  • Maximum modeled package height is consistent with the 0.6 mm class.
  • Pin-1 indication is present.
Footprint mismatch
TI's current DRL0008A recommended land pattern specifies eight 0.30 mm × 0.67 mm pads. The footprint asset uses 0.30 mm × 0.475 mm pads. The pad width is correct, but each pad is approximately 0.195 mm shorter than TI's recommended land length.
This is a manufacturing-relevant mismatch. The footprint may still solder under a qualified custom process, but it does not match TI's current recommended land pattern and should be corrected or formally validated before production use.

Overall Assessment
The MPN, manufacturer, datasheet, terminal count, symbol pin names/numbers, and basic body geometry are correct. The part should not be considered fully verified for production because the footprint pads are shorter than TI's recommended land pattern, the package metadata says TO instead of DRL/SOT-5X3, the device is incorrectly classified as Logic / AND, and all pin types/descriptions are unspecified.
