DRV8311 Datasheet Audit

flux

Audit complete against the official TI DRV8311 Rev. B datasheet.
  • Metadata: MPN and manufacturer are correct. Package is RRW0024A, 24-pin 3 × 3 mm WQFN plus exposed pad 25, 0.4 mm pitch.
  • Key specs: 3–20 V operation, 24 V absolute maximum, 5 A peak output, 200 kHz PWM, 10 MHz SPI/tSPI, 210 mΩ typical combined MOSFET on-resistance, and 3.3 V/100 mA AVDD output.
  • Pin numbering/names: All 25 terminals match the DRV8311P datasheet.
  • Datasheet: A URL was already set, so no property update was required.
  • Symbol issues: All terminals lack Pin Description metadata. OUTA/B/C and SOA/B/C are typed Unspecified; AVDD is incorrectly typed Power In despite being a regulator output.
  • Footprint: Perimeter pads, 0.4 mm pitch, 0.2 × 0.47 mm lands, and 1.9 mm exposed pad match TI’s nominal pattern. However, five extra 0.5 mm circular copper pads numbered 26–30 appear beneath the exposed pad without drill definitions; these do not match TI’s optional ~0.2 mm thermal vias and may cause incorrect mask/paste behavior.
I filed an internal part-quality report for the footprint and symbol metadata issues.

Update every terminal with the datasheet pin description and correct the pin electrical types.

flux

I’ll update all 25 terminals from TI’s pin-function table, correct each electrical type, and verify the full terminal set afterward.

flux

Updated and verified all 25 terminals against the TI datasheet.
  • Added complete Pin Description properties.
  • Corrected all electrical types, including Power Out for CP/AVDD, Output for motor and CSA outputs, and Not Connected for pins 13/18.
  • Confirmed pin numbers 1–25 are present exactly once with no omissions or duplicates.
