Part Number: TUSB8020B

Dear TI support

As the the hub will be used between two chips, no power control will be required. what is the best connection for the following?

Everything can be left to the default conditions.

These are the most important ones, but they are all handed with the internal pu / pd:

FULLPWRMGMTz should be pulled high

OVERCURz should be pulled high

SMBUSz should be pulled high

Thank you for your answer

so you mean all the above pins "in my post" can be left floating as they are pulled up or down internally?

Best Regards

Yes, that is correct. Default internal pullups will handle the configuration in this case.

You can add external placeholders or test points, but it is not required.
