ISL54220
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.
