pull-down resistor and return to the Audio or Mute mode,
depending on the condition of the CTRL pin.
Note: The ISL54211 contains an internal diode between the
IN pin and VDD pin. Whenever the IN voltage is greater than
the V
this diode into the V
resistor in the range of 100kΩ to 500kΩ is required at the IN
logic pin to limit the current when driving it with the V

USB hub (4.4V to 5.25V) to drive the IN pin while the V
voltage is in the range of 2.7V to 3.6V. A 500kΩ resistor will
limit the current to 3µA to 5µA and still allow the IN logic
voltage to go to around 3V, which is will above the required
