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?
