USB sub-system examples

The following Figure 50. Battery powered application with a USB OTG port and a USB host port,

Figure 51. Battery powered application with a single USB OTG port , and Figure 52. 5 V DC powered application

with a USB OTG port and two USB host ports show some typical USB sub-system configuration examples:

Figure 50. Battery powered application with a USB OTG port and a USB host port

On this example, a battery supplies the boost converter. When enabled, the boost converter generates a 5.2 V on

BSTOUT.

PWR_USB_SW output (VBUSOTG) is connected, in this example, to a USB Type-μAB connector (OTG). It can

alternatively be connected to a USB Type-C connector.

PWR_SW output (SWOUT) is connected, in this example, to a USB Type-A connector (USB host only). PWR_SW

input (SWIN) is connected to the output of boost converter (BSTOUT).
