Hi Team,

Customer is using TUSB8044A and would like to know what the threshold on the USB_VBUS pin is?

    Hello,

    The threshold voltage for VBUS is that the VBUS comparator will be 1 when VBUS is between 3V to 4V. This makes the threshold voltage at the pin roughly 0.3V because of the voltage divider on the VBUS pin. This is not exact because there will be some tolerance in the resistors and comparator.

    Best,
