Description
regulated supply voltage (3.3 V
±
10%) from internal
regulator; used to connect pull-up resistor on DP0 line
modes 4 to 6
: power switch control output for downstream
port 2 (open-drain, 6 mA)
modes 0 to 3, 7
: GoodLink LED indicator output for
downstream port 2 (open-drain, 6 mA); to connect an LED
use a 330
series resistor
ground supply
downstream port 3 D
connection (analog)
[4]
downstream port 3 D
+
connection (analog)
[4]
supply voltage; connect to USB supply V
BUS
(bus-powered or
hybrid-powered) or to local supply V
DD
(self-powered)
overcurrent sense input for downstream port 1 (analog
[5]
)
overcurrent sense input for downstream port 2 (analog
[5]
)
overcurrent sense input for downstream port 3 (analog
[5]
)
overcurrent sense input for downstream port 4 (analog
[5]
)
modes 5, 7
: overcurrent sense input for downstream port 5
(analog
[5]
)
modes 0, 1, 3
: global overcurrent sense input (analog
[5]
)
downstream port 4 D

selects power mode:
self-powered
: connect to V
DD
(local power supply); also use
this mode for hybrid-powered operation
bus-powered
: connect to GND; disable downstream port 5 to
meet supply current requirements

hub GoodLink LED indicator output (open-drain, 6 mA);
to connect an LED use a 330
series resistor; if unused
connect to V
CC
via a 10 k
resistor
modes 4 to 6
: power switch control output for downstream
port 3 (open-drain, 6 mA)
modes 0 to 3, 7
: GoodLink LED indicator output for
downstream port 3 (open-drain, 6 mA); to connect an LED
use a 330
series resistor
modes 4 to 6
: power switch control output for downstream
port 4 (open-drain, 6 mA)
modes 0 to 3, 7
: GoodLink LED indicator output for
downstream port 4 (open-drain, 6 mA); to connect an LED
use a 330
