TYPICAL APPLICATION

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

the figure below, to be powered by VBUS through the microUSB connector. The control pins (SEL1 and SEL2)

have built-in 6M

Ω pull-down resistors to ensure the USB paths are enabled for TS3USB3200 and allow

connectivity to the TSU5611 USB accessory switch.

The TS3USB3200 can also be powered by the mobile device’s standalone battery. The diagram below shows a

typical implementation. The VBUS pin of the TS3USB3200 can simply be grounded under such conditions.
