of the ISL54213 low. As long as the CTRL = Logic “1,” the
ISL54213 part will be in the audio mode and the audio
drivers of the media player can drive the headphones and
play music.
USB Mode
If the IN pin = Logic “1” and CTRL pin = Logic “0” or Logic
“1”, the part will go into USB mode. In USB mode, the D- and
D+ 5.5
Ω switches are ON and the L and R 2.5Ω audio
switches are OFF (high impedance).
When a USB cable from a computer or USB hub is
connected at the common connector, the processor will
sense the presence of the 5V VBUS voltage and drive the IN
pin voltage high. The ISL54213 part will go into the USB
mode. In USB mode, the computer or USB hub transceiver
and the MP3 player or cell phone USB transceiver are
connected and digital data will be able to be transmitted
back and forth.
When the USB cable is disconnected, the processor will
sense that the 5V VBUS voltage is no longer connected and
will drive the IN pin low and put the part back into the Audio
or Mute mode.
Mute Mode
If the IN pin = Logic “0” and CTRL pin = Logic “0”, the part
will be in the Mute mode. In the Mute mode, the audio
switches and the USB switches are OFF (high impedance).
In this state the switches have excellent off-isolation (112dB
over the audio band with a 32
Ω load) for muting of audio
signals.
USING THE COMPUTER VBUS VOLTAGE TO DRIVE THE
“IN” PIN
Rather than using a microprocessor to control the IN logic
pin, one can directly drive the IN pin using the VBUS voltage
from the computer or USB hub. See the application block
diagram in Figure 9.
When a headphone or nothing is connected at the common
connector, the internal 4M
Ω pull-down will pull the IN pin low
putting the ISL54213 in the Audio or Mute mode, depending
on the condition of the CTRL pin.
When a USB cable is connected at the common connector,
the voltage at the IN pin will be driven to 5V and the part will
automatically go into the USB mode.
When the USB cable is disconnected from the common
connector, the voltage at the IN pin will be pulled low by the
pull-down resistor and return to the Audio or Mute mode,
depending on the condition of the CTRL pin.
Note: The ISL54213 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 2.5V to 3.6V. A 500k
Ω resistor will
limit the current to 2.76A and still allow the IN logic voltage
to go to around 3.67V 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.
