Port 2 Power

Output

PRTPWR2

Enables power to a downstream USB device

attached to Port 2.

0 = Power disabled on downstream Port 2

1 = Power enabled on downstream Port 2

Port 2 Control

PRTCTL2

OD8/IS

(PU)

When configured as PRTCTL2, this pin functions

as both the Port 2 power enable output

(PRTPWR2) and the Port 2 over-current sense

input (OCS2_N). Refer to the PRTPWR2 and

OCS2_N descriptions for additional information.

Port 2 Battery

Charging

Configuration

Strap

BC_EN2

This strap is used to indicate support of the

battery charging protocol on Port 2. Enabling

battery charging support allows a device on the

port to draw currents per the USB battery

charging specification.

0 = Battery charging is not supported on Port 2

1 = Battery charging is supported on Port 2

See Note 3.4 for more information on

configuration straps.

Port 3 Power

Output

PRTPWR3

Enables power to a downstream USB device

attached to Port 3.

0 = Power disabled on downstream Port 3

1 = Power enabled on downstream Port 3

Port 3 Control

PRTCTL3

OD8/IS

(PU)

When configured as PRTCTL3, this pin functions

as both the Port 3 power enable output

(PRTPWR3) and the Port 3 over-current sense

input (OCS3_N). Refer to the PRTPWR3 and

OCS3_N descriptions for additional information.

battery charging support allows a device on the

port to draw currents per the USB battery

charging specification.

0 = Battery charging is not supported on Port 3
