Description

The DIODES PI3USB3031 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 al-

low 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 PI3USB3031 has a VCC range of 1.8V to 5.5V and supports

overvoltage tolerance (OVT) feature, which allows the I/O pins to

withstand overvoltage conditions (up to 5.5 V). The power-off pro-

tection 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 PI3USB3031 are compatible with 1.8V 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 PI3USB3031 comes with a small 12-pin VQFN package with

only 1.8mm x 1.8mm and QFN package with only 1.6mm x 1.6mm

in size, which makes it a perfect candidate to be used in mobile

applications.
