Figure 9-3. OSPI Interface High Level Schematic
9.2.3 USB VBUS Design Guidelines
The USB 3.1 specification allows the VBUS voltage to be as high as 5.5 V for normal operation, and as high as
20 V when the Power Delivery addendum is supported. Some automotive applications require a max voltage to
be 30 V.
The device requires the VBUS signal voltage be scaled down using an external resistor divider (as shown in
the Figure 9-4), which limits the voltage applied to the actual device pin (USB0_VBUS). The tolerance of these
external resistors should be equal to or less than 1%, and the leakage current of zener diode at 5 V should be
less than 100 nA.(1)
