1.VBUS_DET PIN is connected to VBUS with a 900K resistor, and there is a 95K pull-down resistor inside the TUSB321. After USB is inserted in actual measurement, VBUS_DET PIN is only 0.5V. I would like to know the VBUS_DET voltage threshold judged as USB insertion.
2.Can TUSB321 be powered by VBUS? If VBUS is used for power supply, does it affect CC detection?
