DRV8906-Q1: AGND and PGND difference?

Yoshiki Ochi

Part Number: DRV8906-Q1

Hi team,

"11.1 Layout Guidelines" has "PGND" and "AGND" explanation. Could you tell me which GND is "AGND" and which is "PGND2 shown in "11.2 Layout Example"?

Regards,
Ochi

Hi Ochi san,

Thank you for good question. Pin 13,24 are PGND. Pin 1 is PGND+AGND internally. We are expecting all GND pins are connected externally on GND plane under DRV, however Pin1 is AGND+PGND internally.
