Description
The PI3USB223 combines AC coupled audio signals and USB2.0
HS (480Mbps) on the same pins. This enables users to use a single
connector to drive either a USB end point or an audio end point.
PI3USB223 incorporates gate pump technology required to main-
tain low Ron for ideal audio THD while reducing the capacitance
affect of high speed USB signals. The device also incorporates a
substrate pump technology which allows -2Vsignals to pass through
the switch without causing any leakage.
The PI3USB223 features protection on D+/R and D-/L to ensure no
damage will happen to the IC if these pins are shorted accidentally
to Vbus as well as ensuring there is no leakage when VDD is on or
off. Also, it includes VBUS detection (VB) to automatically switch
to the USB signal path upon detection of a valid VBUS signal. It
also features internal shunt resistors on the audio path to reduce
clicks and pops heard during output. The device is available in a
space-saving 10-pin, 1.4mm x 1.8mm UQFN package, and operate
over the -40°C to +85°C temperature range.

Switch SEL to override VBUS detection when VBUS and VDDare both high.
If ASEL is HIGH, then audio path will be on
If ASEL is LOW then USB path will be on ASEL has an internal 3M-ohm pull-down
If ASEL is tied LOW, then VBUS detection can be used for auto switching. If ASEL is LOW
VBUS = HIGH means USB path is active
