Hi Expert,

My customer have some question for TUSB4020BI.

What kind of operation is SMBUS Programming for SMBUS Programming current spec :225mA?

Can the customer ship with default registers condition that is included VID and PID registers?

Thanks

Hi Muk,

In SMBUS mode TUSB4020BI wait to be programmed before starting normal operation. This means USB devices on the downstream port will not be able to connect to USB Host. The default VID and PID can be used by the customer.
