8 Detailed Description

8.1 Overview

The TS5USBC400 is a bidirectional low-power dual port, high-speed, USB 2.0 analog switch with integrated protection for USB Type-C systems. The device is configured as a dual 2:1 or 1:2 switch and is optimized for handling the USB 2.0 D+/- lines in a USB Type-C system as shown in Figure 13.

The TS5USBC400 also works in traditional USB systems that need protection from fault conditions such as automotive and applications that require higher voltage charging. The device maintains excellent signal integrity through the optimization of both RON and BW while protecting the system with 0 V to 16 V OVP protection. The OVP implementation is designed to protect sensitive system components behind the switch that cannot survive a fault condition where VBUS is shorted the D+ and D- pins on the connector.

8.3 Feature Description

8.3.1 Powered-off Protection

When the TS5USBC400 is powered off the I/Os of the device remain in a high-Z state. The crosstalk, off-isolation, and leakage remain within the Electrical Specifications.

This prevents errant voltages from reaching the rest of the system and maintains isolation when the system is powering up.

8.3.2 Overvoltage Protection

The OVP of the TS5USBC400 is designed to protect the system from D+/- shorts to VBUS at the USB and USB Type-C connector. Figure 14 depicts a moisture short that would cause 16 V to appear on an existing USB solution that could pass through the device and damage components behind the device.

The TS5USBC400 will open the switches and protect the rest of the system by blocking the 16 V as depicted in .

Figure 16 is a waveform showing the voltage on the pins during an over-voltage scenario.
