8.3.2 Overvoltage Protection

The OVP of the TS5USBC41 is designed to protect the system from D+/- shorts to VBUS at the USB and USB Type-C connector. Figure 17 depicts a moisture short that would cause high voltage (20 V for TS5USBC410 or 20 V for TS5USBC412) to appear on an existing USB solution that could pass through the device and damage components behind the device.

The TS5USBC41 will open the switches and protect the rest of the system by blocking the 20 V / 24 V as depicted in Figure 18.
