Hello
From the below pin function description in the TUSB8041 datasheet,
FULLPWRMGMTz/ SMBA1/SS_UP has internal PD.
But on the same time, there is a description “Can be left unconnected if full power management and SMBus are not implemented.”
It means if it is left unconnected, FULLPWRMGMT=1. I think it is strange because this pin should have internal PD.
Does this pin really has internal PD, not PU?
Regards,
Oba
