Pin Function Grouping
Worked for 46 sec
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.
Thought for 6 sec
I’ll generalize the pin group names and mirror each pin’s final Pin Group into its Section property.
Worked for 34 sec
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.
