9.2.1.2.4 Downstream Port 3 Implementation

The downstream port3 of the TUSB8043A is connected to a USB3 Type A connector. With BATEN3 pin pulled up, Battery Charge support is enabled for Port 3. If Battery Charge support is not needed, then pull-up resistor on BATEN3 should be uninstalled. For ferrite bead used on the VBUS connection, a lower resistance is recommended due to noticeable IR drop during high current charging modes. The isolation between the Type-A connectors shield ground and signal ground pins is not required. Some applications may have better ESD/EMI performance when the grounds are shorted together.
