Functional Description
The FSA223 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 high-speed USB signals and
includes an automatic VCC-detection circuit. The
FSA223 detects the presence of VCC and defaults to
USB mode. Both the USB and audio switch paths
also handle negative signals, which eliminates the
need for large coupling capacitors.
The ASel pin is internally terminated by a resistor to
GND (typical value: 3 M
Ω) and results in a default
USB connection. For optimal performance, VCC
should be connected directly to the device battery.
