Hi dear support team,
I am designing a board using ADUM4160, to insert a USB isolation on an existing previous design, and I need a confirmation about PIN input .
See attached pictures for clarification.
In the previous design, the MCU was controlling ENUM (USB_RENUM 3V3 signal) through a BC847B transistor.
In the new design, if I understand correctly, I can connect USB_RENUM output from MCU directly to ADUM4160 PIN input, for same effect, right?
Is the second schematic ok in the picture?
Should I add a pull-up resistor on PIN input, like on 4160 demo board? I guess no...
Thanks very much
