Part Number: TUSB320LI
Other Parts Discussed in Thread: PMP4494

Dear Sir：

             Reference to PMP4494, EN_N is pulled high to 3.3V. But it is asked to set ative low by reference to SPEC.

             So how should I set EN_N ?

             Thank you and expect your reply.

 

 

best wishes,

    Hello Faith,

        EN_N is an active low input, therefore you need to use either way a GPIO with a LOW state or a pull-down resistor. to disable the device it is enough to leave the input floating or connecting to a pull-up resistor.
