At which level of voltage is USB - device disconnected
I have to realize an USB - Switch on my own. For security I have a chip (TPS2052) which has a short - circuit protection and is controlling the current.
My problem is: When I switch from one USB - Port to antoher the chip TPS2052 has an delay (ms - range) until it is from 5V to 0V. I have to do some testing with my USB - Switch circuit. So I have to know exactly when the USB - Device is disconnected. Can you tell me at which level of voltage the USB - device is disconnected?
