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 5.5 V, which can be dam-

aging 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

mode

Port 1 Type-C

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.

Note 3-4

If unused: Weak pull-down

to GND. This pin may only

be left unused if Port 1 is

disabled or reconfigured to

operate in legacy Type-A
