VBUS Detect

VBUS_DET

This signal detects the state of the upstream bus power

in legacy Type-B upstream implementations.

When designing a detachable hub, this pin must be con-

nected to the VBUS power pin of the upstream USB port

through a resistor divider (50 k

Ω by 100 kΩ) to provide

3.3 V.

For self-powered applications with a permanently

attached host, this pin must be connected to either 3.3 V

or 5.0 V through a resistor divider to provide 3.3 V.

In embedded applications, VBUS_DET may be con-

trolled (toggled) when the host desires to renegotiate a

connection without requiring a full reset of the device.

Port 1 Type-C

Voltage Monitor

DP1_VBUS_MON

I/O12

Used to detect Type-C VBUS vSafe5V and vSafe0V

states on Port 1. A potential divider is needed for this pin

(43 k

 to 49.9 k , 1.0%).

CC1

DP1_CC1

I/O12

Used for Type-C attach and orientation detection on Port

1. Includes configurable Rp/Ra selection. Connect this

pin directly to the CC1 pin of the respective Type-C con-

nector.
