USB Type-C^® features bi-directional connection and broad specification applications supporting USB 3.2, USB4, DisplayPort, Thunderbolt, HDMI, etc., as well as capability to support charging up to 100W that allows derivation to quick charging specifications by various vendors.

Due to the compact size of USB Type-C^® connector which spacing between pins are extremely close, any sliding or dislocation in contact point or moisture to connector, or cables and equipment with poor design would cause short circuit in Vbus to CC or SBU pin, in which a damage to CC or SBU would occur when Vbus voltage exceeds 5V. Therefore, CC and SBU pins require the maximal VBUS 24V voltage tolerance under USB PD specifications to avoid damages resulting from short circuit.

For a holistic overvoltage protection plan, in addition to OverVoltage Protection (OVP), whether there is Energy Clamping protection mechanism to correspond to ringing resulting from Cable and RLC from system board, instantaneous voltage reaching 40V, or lapse longer than ESD in the OVP switch duration shall be considered. Within the switch duration, the single-chip plan featuring OVP, Energy Clamping and ESD is your best choice!
