USB Type-C Connector Control

Downstream

Port 1 Type-C

Voltage Monitor

DP1_VBUS_MON

AIO

Used to detect Type-C VBUS vSafe5V and

vSafe0V states on Port 1. Externally, VBUS

can be as high as 5.25 V, which can be

damaging to this pin. The amplitude of

VBUS must be reduced by a voltage divider.

The recommended voltage divider is shown

below. 1% tolerance resistors are recom-

mended.

Note:

For proper Type-C port opera-

tion, it is critical that this pin actu-

ally be connected to VBUS of the

port through the recommended

resistor divider. This pin should

not be tied permanently to a

fixed voltage power rail.

Note 3-3

If unused: Weak pull-down

to GND. This pin may be

left unused if Port 1 is

disabled or reconfigured to

operate in legacy Type-A

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.

Note 3-4

If unused: Weak pull-down
