High voltage protection

The STUSB4761 can be safely used in systems or connected to systems that handle high voltage on the VBUS

power path. The device integrates an internal circuitry on the CC pins that tolerates high voltages and ensures

protection up to 22 V in case of unexpected short-circuits with the VBUS.

Short to 22 V is guaranteed as per figure below.
