Hi Lenna,

Please find the threshold setting in GUI. You can find details in https://www.ti.com/lit/ug/slvubh2b/slvubh2b.pdf?ts=1609950092638.

Please let me know if you need further help.

Thanks

Hi Prajith，

Thanks for your reply. So the threshold is defined by the customer self. Is it right? Is there recommended setting for the threshold?

Hi Lenna,

Yes, user has to define the threshold level. Setting for threshold depends on what functionality you want to implement. For instance, you can use GPIO to control power to a circuit when the Vbus voltage from far-end goes above certain voltage limit.

Thanks
