8.2.2 TS3USB3200 Powered by Mobile Device’s Standalone Battery

The TS3USB3200 can also be powered by the mobile device’s standalone battery. Figure 19 shows a typical

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

8.2.2.1 Design Requirements

The TS3USB3200 can be properly operated without any external components. However, TI recommends that

unused pins must be connected to ground through a 50-Ω resistor to prevent signal reflections back into the

device.

8.2.2.2 Detailed Design Procedure

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

9 Power Supply Recommendations

Power to the device is supplied through the VCC pin and must follow the USB 1.0, 1.1, and 2.0 standards. TI

recommends placing a bypass capacitor as close to the supply pin VCC as possible to help smooth out lower

frequency noise to provide better load regulation across the frequency spectrum.
