8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

For Mobility Display Port Applications (MyDP) the signal voltage must be biased to ensure that the signal never

outside the range of 0 V to 3.6 V.

The control pins (SEL1 and SEL2) have built-in 6-MΩ pulldown resistors to ensure the USB paths are enabled

for TS3USB3200 and allow connectivity to the TSU5611 USB accessory switch.

8.2 Typical Applications

8.2.1 TS3USB3200 Configured to be Powered by VBUS Through the MicroUSB Connector

During manufacturing test when battery power is not available, the TS3USB3200 can be configured, as shown in

Figure 10, to be powered by VBUS through the microUSB connector.

8.2.1.1 Design Requirements

Design requirements of the MHL and USB 1.0,1.1, and 2.0 standards must be followed. The TS3USB3200 has

internal 6-M

Ω pulldown resistors on SEL and OE, so no external resistors are required on the logic pins. The

internal pulldown resistor on SEL ensures the USB channel is selected by default. The internal pulldown resistor

on OE enables the switch when power is applied to VCC.
