DESCRIPTION
The TSU6712 is
a multiple SP4T switch with
APPLICATIONS
impedance detection. The switch features impedance
detection, which supports the detection of various
accessories that are attached through DP and DM.
The detection is based on the impedance values of
the accessories as defined in Table 1. The TSU6712
is fully controlled using I2C and enables USB data,
stereo and mono audio, video, microphone, and
UART data to use a common connector port.

Power for this device is supplied through VBAT of the
system or through VBUS when attached. The switch
can be controlled through I2C. JIG and BOOT pins
are used when a USB, UART JIG cable is used to
test during development and manufacturing.
