Pin Function Grouping

flux

Grouped and ordered all pins by function:
  • Power: VM
  • Ground: GND pin 7, exposed pad pin 9
  • Control: IN1, IN2, VREF
  • Current Sense: IPROPI
  • Motor Outputs: OUT1, OUT2
Pin orientation and ordering were also set consistently.

Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.

There are 9 terminals, so a unique sequence from 1–10 requires one unused number. Also, the three remaining sections—Control, Current Sense, and Motor Outputs—cannot each have a different orientation using only Left and Right.
Should I proceed with this practical mapping?
  • VM: 1, Top
  • Control pins: 2–4, Left
  • Current Sense: 5, Right
  • Motor Outputs: 6–7, Right
  • Ground pins: 9–10, Bottom
  • Terminal Order 8 unused

Use orders 1–9 instead, with both Ground terminals last at 8 and 9.

Assigned terminal orders 1–9:
  • VM: 1, Top
  • IN1–VREF: 2–4, Left
  • IPROPI–OUT2: 5–7, Right
  • GND terminals: 8–9, Bottom
