Pin cross-check
The schematic symbol contains all 45 terminals and the footprint contains 45 pads. Most pin numbers and names match the datasheet for the physical DDW package. The exposed thermal pad is represented as EP with Pin Number 45, which is appropriate for the land/pad count even though the TI pin table labels it as PAD rather than a numbered signal pin.
Mismatches / issues
  1. Datasheet URL was not the official TI URL in project metadata
  2. Library/project description overstates headline ratings
    • Current description says “70-V 20A single or dual H-br”.
    • Datasheet headline is 60-V operating VM. 70 V is the absolute maximum VM rating, not operating rating.
    • Datasheet output current is 16 A peak / 10 A RMS recommended in single H-bridge mode, and 8 A peak / 5 A RMS recommended in dual H-bridge mode. A generic “20 A” description is not supported by the reviewed datasheet excerpts.
  3. Dual H-bridge functional labels for IPROPI are swapped
    • Datasheet: Pin 30 = IPROPI2; Pin 31 = IPROPI1.
    • Symbol: Pin 30 is named IPROPI_1; Pin 31 is named IPROPI_2.
    • Recommended fix: rename Pin 30 to IPROPI2 and Pin 31 to IPROPI1, or use datasheet dual-mode aliases in pin descriptions.
  4. Dual H-bridge functional labels for VREF are swapped
    • Datasheet: Pin 33 = VREF2; Pin 34 = VREF1.
    • Symbol: Pin 33 is named VREF_1; Pin 34 is named VREF_2.
    • Recommended fix: rename Pin 33 to VREF2 and Pin 34 to VREF1.
  5. Pins 38 and 39 omit dual-mode function names
    • Datasheet: Pin 38 = RSVD in single H-bridge mode / IN4 in dual H-bridge mode; Pin 39 = RSVD in single H-bridge mode / IN3 in dual H-bridge mode.
    • Symbol: RSVD_3 and RSVD_4 only.
    • Recommended fix: label as RSVD/IN4 and RSVD/IN3, or add pin descriptions with dual-mode aliases.
  6. Pin metadata is incomplete
    • All terminal Pin Type fields are currently “Unspecified”.
    • No terminal-level Pin Description fields are present.
    • Recommended fix: populate Pin Type and Pin Description from the datasheet pin table, especially for power pins, logic inputs, open-drain nFAULT, analog outputs IPROPIx, reserved pins, and charge-pump pins.
Footprint check
  • Footprint has 44 perimeter pads plus exposed thermal pad = 45 pads; this matches the datasheet terminal count.
  • Pad naming/designators correspond to symbol terminals.
  • Datasheet land pattern expects HTSSOP-44 PowerPAD, 0.635 mm pitch, pin land pads 1.45 mm x 0.4 mm, thermal pad land about 3.8 mm x 8.0 mm, with thermal via array guidance.
  • This review verified pad count and terminal mapping from available layout data. It did not independently measure pad dimensions because the current layout tree response did not expose pad geometry values.
  • Update the part description to a datasheet-accurate rating such as: “Automotive 60-V single/dual H-bridge motor driver, 16-A peak single or 8-A peak dual, HTSSOP-44 PowerPAD.”
  • Rename swapped VREF/IPROPI pins or add explicit pin descriptions with single-mode and dual-mode aliases.
  • Add Pin Type and Pin Description properties for all terminals from the datasheet pin table.
  • If footprint geometry data is available in a deeper footprint editor view, verify pad dimensions against TI DDW0044E land pattern values.
