ISL54221
In addition when V_DD is at 0V (ground) all switches are OFF
and the shorted V_BUS voltage is isolated from the other side
of the switch. When V_DD is in the range of 2.7V to 5.5V the
shorted V_BUS voltage will pass through to the output of an
active (turned ON) switch channel but not through a turned
OFF channel. Any components connected on the active
channel must be able to withstand the overvoltage condition.
Note: During the fault condition normal operation of the USB
channel is not guaranteed until the fault condition is
removed.
