SCDS337 – DECEMBER 2012

TYPICAL APPLICATION

Figure 1 represents a typical application of the TS3USB3000 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 6M

Ω pull-down resistors on SEL and OE. The

pull-down on SEL ensure the USB channel is selected by default. The pull-down 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.
