ES9822QPRO Review

flux

Assigned pin orientation, section, and terminal order for all 41 existing ES9822QPRO terminals and verified the updates. Power pins are ordered first, ground/EPAD last, and the larger Digital/NC groups are split across left/right for readability.
Open items:
  • Per your instruction, I did not rename pins; note pin 40 is still labeled DGND_2 even though the datasheet function is RT1.
  • Pin 41 remains labeled DGND_3, but is organized as the final Ground/EPAD terminal.
Suggested next steps:
  1. Rename pin 40 to RT1 and pin 41 to EPAD if you want the symbol labels corrected.
  2. Populate Pin Type and Pin Description from the datasheet.

Distribute all pins approximately evenly between the Left and Right sides of the schematic symbol.
Place power pins at the Top and first in Terminal Order. Place GND pins at the Bottom, Left, or Right and last in Terminal Order.
Keep related pins together, balance the symbol, and do not change pin names, numbers, or mapping.

I’ll rebalance the existing symbol metadata only: keep power at top/order first, keep GND/EPAD last, and split the remaining functional groups roughly evenly left/right without changing names, numbers, or mappings.

flux

Rebalanced the symbol metadata while preserving all pin names, numbers, and mappings. The non-power/non-ground pins are now split approximately evenly: 14 Left and 15 Right, with power pins Top/orders 1–7 and GND/EPAD Bottom/orders 37–41.
Open items:
  • None for this requested metadata change.
Suggested next steps:
  1. Review the rendered symbol for visual spacing.
  2. Optionally correct labels for pin 40 (RT1) and pin 41 (EPAD) in a separate pass.
