EXTERNAL SERIES RESISTOR AT IN LOGIC CONTROL
PIN
The ISL54208 contains a clamp circuit between IN and VDD.
Whenever the IN voltage is greater than the VDD voltage by
more than 2.55V, current will flow through this clamp circuitry
into the VDD power supply bus.
During normal USB operation, VDD is in the range of 2.7V to
3.6V and IN (VBUS voltage from computer or USB hub) is in
the range of 4.4V to 5.25V, the clamp circuit is not active and
no current will flow through the clamp into the VDD supply.
In a USB application, the situation can exist where the VBUS
voltage from the computer could be applied at the IN pin
before the VDD voltage is up to its normal operating voltage
range and current will flow through the clamp into the VDD
power supply bus. This current could be quite high when
VDD is OFF or at 0V and could potentially damage other
components connected in the circuit. In the application
circuit, a 22kΩ resistor has been put in series with the IN pin
to limit the current to a safe level during this situation.
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
VBUS is present before VDD is up to its normal operating
voltage.
Note: No external resistor is required in applications where
IN pin voltage will not exceed VDD by more than 2.55V.
