ISL54206A
It is recommended that a current limiting resistor in the
range of 10kΩ to 50kΩ be connected in series with the IN
pin. It will have minimal impact on the logic level at the
IN pin during normal USB operation and protect the
circuit during the time V_BUS is present before V_DD is up
to its normal operating voltage.
Note: No external resistor is required in applications
where the voltage at the IN pin will not exceed V_DD by
more than 2.55V.
