Pin Type Description
Vreg(3.3) [2]
1
-
regulated supply voltage (3.3 V ± 10%) from internal
regulator; used to connect pull-up resistor on DP0 line
PSW2/GL2 [3] 2
O
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 Ω series resistor
GND
3
-
ground supply
DM3
4
AI/O downstream port 3 D− connection (analog) [4]
DP3
5
AI/O downstream port 3 D+ connection (analog) [4]
VCC
OC1
6
-
supply voltage; connect to USB supply VBUS (bus-powered or
hybrid-powered) or to local supply VDD (self-powered)
7
AI/I overcurrent sense input for downstream port 1 (analog [5])
OC2
8
AI/I overcurrent sense input for downstream port 2 (analog [5])
