TUSB8041: Unused pins - SMBUS

Part Number: TUSB8041

Hello Team,

We do no need power management or SMBus on the customer product so we plan to leave the FULLPWRMGMTz/SMBA1/SS_UP (pin 40) unconnected as stated in the device datasheet (page 7).

The question is what to do with the following pins:

  • PWRCTL_POL (pin 41)
  • GANGED/SMBA2/HS_UP (pin 42)
  • AUTOENz/HS_SUSPEND (pin 45)

 Can we leave these pins unconnected or is it better to select some configuration, regardless if power management and SMBus features are not used?
