Review date: 2026-07-20 Part project: DRV2901DDV
Completed the review and added the official TI datasheet URL: https://www.ti.com/lit/ds/symlink/drv2901.pdf.
I created the full findings in DRV2901DDV Part Information Review. Key result: the symbol pinout is functionally correct, but the part needs cleanup before production use — pin types/descriptions are missing, the active-low pin names differ from TI labels, the MPN should likely be the orderable DRV2901DDVR, and the footprint appears to be missing the exposed PowerPAD thermal pad.
Check this schematic component against the datasheet for [MPN] and assign the correct pin orientation, section, and terminal order without changing, replacing, renumbering, or remapping any pins. Place Power pins first , Ground pins last , and distribute all other pins evenly along the left and right edges so the symbol remains compact, balanced, and approximately symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
I’ll update the existing DRV2901 terminals in place: set orientation/section/order from the TI datasheet while preserving every current pin number and terminal mapping.
Updated the DRV2901 schematic component in place against the TI datasheet. I preserved all existing pin numbers, designators, and mappings.
Open items:
  • No unclear pins were found; all terminals were assigned to Power, Signal, No Connect, or Ground.
  • Pin types/descriptions were not changed because your request was limited to orientation, section, and terminal order.
Suggested next steps:
  1. Update pin types and pin descriptions from the datasheet for better ERC behavior.
  2. Correct the footprint PowerPAD issue flagged earlier.
  3. Set the orderable MPN to DRV2901DDVR if this part should be BOM-ready.
