7 Detailed Description

7.1 Overview

The TS3USB3200 supports high-speed Mobile High-Definition Link (MHL) or Mobility Display Port (MyDP) switching, as well as USB 2.0 High-Speed (480 Mbps) switching in the same package. An additional integrated ID switch is also included to support USB/MHL or MyDP ID for easy information control. These configurations allow the system designer to use a common USB or Mico-USB connector to support both MHL/MyDP video signals and USB data.

7.3 Feature Description

7.3.1 Flexible Power Control

Device can be powered by VBUS or by VCC. This allows the device to run off a 4.3-V battery voltage or 5 V from an external USB device. If both a battery and external USB device are supplying voltage on the VCC and VBUS pins the PSEL can be used to select which power supply is used to save battery power.

7.3.2 IOFF Protection Prevents Current Leakage in Powered Down State (VCC and VBUS= 0 V)

When there is no power supplied to the IC, all of the I/O signal paths are placed in a high impedance state, which isolates the data paths when they are not being used.

7.3.3 1.8-V Compatible Control Inputs (SEL1, SEL2, and PSEL)

The TS3USB3200 logic control input pins can operate with 1.8-V logic since the VIH minimum for the SEL1, SEL2, and PSEL is 1.3 V.

7.4 Device Functional Modes

The TS3USB32000 device can select which power supply pin VCC or VBUS will power the device when voltages are present on both pins.

VCC VBUS PSEL(1) POWER SOURCE
L L X No Power. All I/O in High-Z
L H X VBUS
H L X VCC
H H L VCC
H H H VBUS
(1) The PSEL pin has 6-MΩ weak pulldown resistor to GND to make its default value to be LOW.
