UPD360

Type-C

Attach

ATTACH

In the Standalone UFP and Standalone DFP modes

(UPD360-A/UPD360-B only), this signal indicates that the

USB Type-C receptacles at the near and far end of the

cable both have a plug-in. This pin is autonomously driven

by the device in DFP standalone mode.

0b: Nothing attached

1b: USB Type-C port has an end-end attached

Refer to Section 9.10, "Standalone DFP (UPD360-A/

UPD360-B Only)" and Section 9.11, "Standalone UFP

(UPD360-A/UPD360-B Only)"for additional information.

Note:

Float this signal when unused.

Note:

This signal is not available in the UPD360-C.

Type-C

Orientation

ORIENTATION

In the Standalone UFP and Standalone DFP modes

(UPD360-A/UPD360-B only), this signal is used to indicate

which CC pin is terminated by the attached DFP/UFP and

is autonomously driven by the device in DFP standalone

mode.

DFP:

0b: CC1 pin is terminated by Rd.

1b: CC2 pin is terminated by Rd.

UFP:

0b: CC1 pin is pulled to a higher voltage than CC2.

1b: CC2 pin is pulled to a higher voltage than CC1.

Refer to Section 9.10, "Standalone DFP (UPD360-A/

UPD360-B Only)" and Section 9.11, "Standalone UFP

(UPD360-A/UPD360-B Only)"for additional information.

Note:

Float this signal when unused.

Note:

This signal is not available in the UPD360-C.

Over-current

sense

OCS_N

OD8

In the Standalone DFP mode (UPD360-A/UPD360-B only),

this active-low signal indicates over-current sense. This sig-

nal maps to the PPC_INT interrupt.

Note:

This signal is active-low. Float this signal when

unused.

Note:

This signal is not available in the UPD360-C.

VBUS Power

Enable

PWR_EN

In the Standalone DFP mode (UPD360-A/UPD360-B only),

this signal is used as a port power switch enable for USB

hubs.

Note:

This signal should be tied to the Power Good

signal from the VS supply.

Note:

Tie this signal to ground when unused.

Note:

This signal is not available in the UPD360-C.
