The TS3USB3031 device is a 2-channel, 1:3 multiplexer that includes a high-speed Mobile
High-Definition Link (MHL), Mobility Display Port (MyDP) switch, and USB 2.0 High-Speed (480 Mbps)
switches in the same package. These configurations allow the system designer to save board space
and eliminate multiple connectors buy using a common USB or Mico-USB connector for MHL/MyDP signals
and two sets of USB data. The MHL/MyDP path supports the latest MHL Rev. 3.0 specification.
The TS3USB3031 has a VCC range of 2.5 V to 4.3 V and supports
overvoltage tolerance (OVT) feature, which allows the I/O pins to withstand overvoltage conditions
(up to 5.5 V). The power-off protection feature forces all I/O pins to be in high impedance mode
when power is not present, allowing full isolation of the signals lines under such condition
without excessive leakage current. The select pins of TS3USB3031 are compatible with 1.8-V control
voltage, allowing them to be directly interfaced with the General Purpose I/O (GPIO) from a mobile
processor with out needing additional voltage level shifting circuitry.
The TS3USB3031 comes with a small 12-pin VQFN package with only 1.8 mm × 1.8 mm in size,
which makes it a perfect candidate to be used in mobile applications.
