Power-off Protection on Common D+/R, D-/L Ports
The FSA201 is a Double-Pole, Double Throw (DPDT)
multiplexer that combines a low-distortion audio and a
USB2.0 Full-Speed (FS) switch path. This configuration
enables audio and USB data to share a common
connector port. The architecture is designed to allow
audio signals to swing below ground. This means a common
USB and headphone jack can be used for personal media
players and similar portable peripheral devices.

LCD Monitor, TV, and Set-top Box
Since USB2.0 is an industry standard for shared datapath in portable devices, the FSA201 also incorporates
a Vbus detection capability. The FSA201 includes a
power-off feature to minimize current consumption when
Vbus is not present. This power-off circuitry is available
for the common D+/R, D-/L ports only. Typical
applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.

Notes:
1. ASel - Internal resistor to GND provides auto-Vbus detect if there is no external connection. Forcing ASel HIGH
when VAUDIO is present overrides the USB path even if Vbus is present.
2. H - Value is the threshold as defined to meet USB2.0 Vbus requirements and audio supply threshold in a system
(see DC Tables).

FSA201 USB2.0 Full-Speed and Audio Switches with Negative Signal Capability
Pin Assignments
The FSA201 is a combined USB and audio switch that
enables sharing the D+/D- lines of a USB connector with
stereo audio CODEC outputs. The switch is optimized
for full-speed USB signals and includes an automatic
Vbus-detection circuit. When a USB connector, rather
than a headphone, is connected to the ultra-portable
device the switch is automatically configured for fullspeed USB data transfer. If no Vbus is detected, and yet
VAUDIO is present, the switch is configured for the lowdistortion audio switch path. The audio switch path also
handles negative signals (down to -2V), which
eliminates the need for large coupling capacitors.
terminated by a resistor to GND (typical value 3MΩ) and
requires no connection for the standard ultra-portable
(cell-phone, MP3, or Portable Media Player). In an
application where the supply to the FSA201 Vbus pin is
not guaranteed to be removed, a GPIO pin can be used
to switch out of full-speed USB mode into audio mode,
using the ASel pin.
The FSA201 Vbus pin must be connected directly to Vbus
or a supply > 3.8V, not an LDO regulated down to 3.6V
or a Vbat-generated supply that may fall below 3.8V in
normal operation (see the Application Diagram).
For those applications where the Vbus is generated as a
self-powered device or where Vbus is not removed, the
ASel pin provides the ability to switch, under software
control, to the audio path. The ASel pin is internally

Functional Description
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

5. Flatness is defined as the difference between the maximum and minimum values of on resistance over the
specified range of conditions.
6. Guaranteed by characterization, not production tested.
7. On resistance is determined by the voltage drop between the A and B pins at the indicated current through the switch.
