TS3USB3200
SCDS333B – JUNE 2012 – REVISED JULY 2016
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 V_BUS or by V_CC. 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 V_CC and V_BUS
pins the PSEL can be used to select which power supply is used to save battery power.
7.3.2 I_OFF Protection Prevents Current Leakage in Powered Down State (V_CC and V_BUS= 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 V_IH minimum for the SEL1,
SEL2, and PSEL is 1.3 V.
