Hi team,
Our customer is using the USB re-driver TUSB211 in their design. And It's good without any problem.
But they would like to ask another question, if you have any experience before please share with us.
Their USB routing as picture below.
When the USB device already plugged in the USB port and power on the system.
The 5V_Standby power will leakage voltage to 3V3_AUX through D+/D- about 0.2V~0.3V.
(They can see the signal step rising on 3V3_AUX, have you ever faced this problem? How can we avoid this leakage voltage? Add capacitor on the USB 2.0 interface?
Please advise
Thanks
