modes 5, 7
: overcurrent sense input for downstream port 5
(analog

)
modes 0, 1, 3
: global overcurrent sense input (analog

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
[4]
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
series resistor
mode 5
: power switch control output for downstream port 5
(open-drain, 6 mA)
modes 3, 7
: GoodLink LED indicator output for downstream
port 5 (open-drain, 6 mA); to connect an LED use a 330
series resistor
modes 0 to 2
: gang mode power switch control output
(open-drain, 6 mA)
crystal oscillator input (6 MHz)
crystal oscillator output (6 MHz)
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset; connect to V
CC
for power-on reset
(internal POR circuit)
mode selection input; also functions as I

C-bus clock output
(open-drain, 6 mA)
selects individual (HIGH) or global (LOW) power switching
and overcurrent detection; also functions as bidirectional
