6.3.10. USB INTERFACE

The STPC integrates a USB host interface with a

2-port Hub. The only external device needed are

the ESD protection circuits USBDF01W5 and a

USB

power

supply

controller.

Figure

6-16

describes a typical implementation using these

devices.

Figure 6-16. Typical USB implementation

Note 1; The ESD protection will be adequate for most applications. In some instances, problems may occur if the devices on the

USB chain do not have enough power to drive the signals adequately. We therefore recommend that you replace the part with de-

screte components and reduce the value of the capacitor.
