Part Data Review and Validation

flux

I’ll update the existing terminal pin metadata in-place, using the datasheet-derived functions from the previous review and then verify the properties were applied.

flux

Set and verified pin types for all 49 MAX77962EWJ12+T terminals.
Summary:
  • Power inputs: CHGIN_*, BST1, BST2
  • Power outputs: SYS_*, BATT_*, PVL, AVL
  • Grounds: GND_*, PGND_*
  • Switching nodes: LX1_*, LX2_* as Passive
  • I2C/control/sense pins: set to Input, Bi-Directional, or Open Collector as appropriate
  • Added concise Pin Description metadata to every pin
One naming issue remains from the prior review: DISQB_AT appears to represent datasheet pin DISQBAT; I left the designator unchanged and noted that in its pin description.
A

Fix DISQB_AT to match the datasheet pin name DISQBAT.

flux

I’ll rename the existing terminal from DISQB_AT to the datasheet pin name DISQBAT, then verify the symbol metadata still maps it to bump G2.

flux

Renamed DISQB_AT to DISQBAT to match the datasheet.
Verified the terminal still has:
  • Pin Number: G2
  • Pin Type: Input
  • Pin Description: DISQBAT battery-discharge control input.
