Port 1 Power
Output
PRTPWR1 O8 Enables power to a downstream USB device
attached to Port 1.
0 = Power disabled on downstream Port 1
1 = Power enabled on downstream Port 1
Port 1 Control PRTCTL1 OD8/IS
(PU)
When configured as PRTCTL1, this pin functions
as both the Port 1 power enable output
(PRTPWR1) and the Port 1 over-current sense
input (OCS1_N). Refer to the PRTPWR1 and
OCS1_N descriptions for additional information.
Port 1 Battery
Charging
Configuration
Strap
BC_EN1
IS This strap is used to indicate support of the
battery charging protocol on Port 1. 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 1
1 = Battery charging is supported on Port 1
See Note 3.4 for more information on
configuration straps.

Port 2 Power
Output
PRTPWR2 O8 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.

Note 3.2 The LOCAL_PWR pin is sampled during the configuration state, immediately after negation
of reset, to determine whether the device is bus-powered or self-powered. When
configuration is complete, the latched value will not change until the next reset assertion.
To enable dynamic local power switching, the DYNAMIC_POWER register at location
0x4134 must be programmed with 0x41. If dynamic power switching is not required, the
DYNAMIC_POWER register should be left at the default value of 0xC1. Programming may
be performed through the SMBus interface, or permanently via OTP. Refer to the Protouch
MPT User Manual for additional information.
Note 3.3 If using the local power detect function (LOCAL_PWR pin), the NON_REM[1:0]
configuration straps cannot be used to configure the non-removable state of the USB ports.
In this case, the non-removable state of the ports must be configured in internal device
registers via the Protouch tool or SMBus.
Note 3.4 Configuration strap values are latched on Power-On Reset (POR) and the rising edge of
RESET_N (external chip reset). Configuration straps are identified by an underlined
symbol name. Signals that function as configuration straps must be augmented with an
external resistor when connected to a load. Refer to Section 6.3, "Device Configuration
Straps," on page 27 for additional information.

+1.2V Core
Power Supply
VDDCR12 P +1.2V core power supply. A 1.0 μF (<1
Ω ESR)
capacitor to ground is required for regulator
stability. The capacitor should be placed as close
as possible to the device. Refer to Chapter 4,
"Power Connections," on page 20 for power
connection information.
