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

Upstream

Voltage Monitor

VBUS_MON_UP

I/O12

Used to detect VBUS on the upstream port.

Externally, VBUS can be as high as 5.25 V,

which can be damaging to this pin. A nomi-

nal voltage of 2.7V (2.4V min -3.0V max) is

required to detect the presence of vSafe5V.

The amplitude of VBUS must be reduced by

a voltage divider. The recommended voltage

divider is shown below. 1% tolerance resis-

tors are recommended.

Note:

For embedded host applications,

this pin should be controlled by

an I/O on the host processor to a

2.68V logic level.
