Pin Function Grouping


Done — I grouped all 25 DRV8770RGER pins by function using the datasheet-style roles, with each physical pin assigned to exactly one Pin Group.
Groups applied:
  • Power: GVDD
  • Ground: GND, EP
  • Control Inputs: INLA, INLB, MODE, DT, INHA, INHB
  • Gate Drive A: BSTA, GHA, SHA, GLA
  • Gate Drive B: BSTB, GHB, SHB, GLB
  • Reserved / No Connect: NC_1, NC_2, RSVD1–RSVD6
I verified the schematic properties after the update.
  • Make the functional group more general.
  • Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property
I’ll generalize the pin group names and mirror each pin’s final Pin Group into its Section property.
Done — I generalized the functional groups and added Section to every pin with the same value as Pin Group.
Final groups are:
  • Power
  • Ground
  • Control
  • Gate Drive
  • Reserved
I verified all 25 terminals now have both properties populated consistently.
