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 VDD voltage by more than 0.7V, current will flow through
this diode into the VDD power supply bus. An external series
resistor in the range of 100k
Ω to 500kΩ is required at the IN
logic pin to limit the current when driving it with the VBUS
voltage. This allows the VBUS voltage from a computer or
USB hub (4.4V to 5.25V) to drive the IN pin while the VDD
voltage is in the range of 2.7V to 3.6V. A 500k
Ω resistor will
limit the current to 3A to 5A and still allow the IN logic
voltage to go to around 3V, which is will above the required
VINH level of 1.4V. A smaller series resistor can be used but
more current will flow.
Typical Performance Curves TA = +25°C, Unless Otherwise Specified
