Pin Function Grouping

flux

Grouped the TPS48100QDGXRQ1 pins from the TI datasheet and updated each terminal with one functional group only. I also added pin descriptions and corrected standard pin types for VS and the two N.C. pins.
Groups applied:
  • Power: VS
  • Bootstrap Supply: BST
  • Ground: GND
  • Logic Inputs: EN/UVLO, INP1, INP2
  • Diagnostics: ~FLT, SCP_TEST
  • Protection Control: CS_SEL, ISCP, TMR
  • Gate Drive: G2, G1PU, G1PD, SRC
  • Current Sense: CS+, CS-
  • No Connect: N.C_1, N.C_2
Open items:
  • None — every existing terminal is assigned to exactly one group.

  • 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 existing pin groups and mirror each pin’s Pin Group into its Section property, then verify all 19 terminals are covered once.

Done — I generalized the functional groups and set every pin’s Section property to exactly match its Pin Group value.
Final groups:
  • Power: VS, BST
  • Ground: GND
  • Control: EN/UVLO, INP1, INP2, CS_SEL, ISCP, TMR, SCP_TEST
  • Status: ~FLT
  • Output: G2, G1PU, G1PD, SRC
  • Sense: CS+, CS-
  • No Connect: N.C_1, N.C_2
Open items:
  • None — all 19 terminals are covered, and Pin Group equals Section for each pin.
