9.2 Typical Application

Figure 15 represents a typical application of the TS3USB3000 USB/MHL switch. The TS3USB3000 is used to switch signals between the USB path, which goes to the baseband or application processor, or the MHL path, which goes to the HDMI to MHL bridge. The TS3USB3000 has internal 6-MΩ pulldown resistors on SEL and OE. The pulldown on SEL ensure the USB channel is selected by default. The pulldown on OE enables the switch when power is applied. The TS5A3157 is a separate SPDT switch that is used to switch between MHL’s CBUS and the USB ID line that is needed for USB OTG (USB On-The-Go) application.
