The TPD3S713x-Q1 is a single-chip solution for short-to-battery, short-circuit, and ESD protection for high-speed data and power lines in automotive USB hub, head unit, telematics, and media interface applications. The integrated data switches provide best-in-class bandwidth for minimal signal degradation during USB short-to-battery events. The high bandwidth of 1.2 GHz allows for a clean USB2.0 high-speed 480-Mbps eye diagram with the long captive cables that are common in the automotive USB environment.
The short-to-battery protection isolates the internal system circuits from any overvoltage conditions at the V BUS, DP_IN, and DM_IN pins. On these pins, the TPD3S713x-Q1 can handle overvoltages up to 18 V for hot plug and DC events and shut off the internal switches to the upstream transceiver from harmful voltage and current spikes.
The V BUS pin also provides an adjustable current limited load switch from 50 mA to 600 mA, which provides flexibility and also saves system power budget when the port requires only several tens of milliampere.
The TPD3S713x-Q1 device has a current-sense output that is able to control an upstream supply, which allows it to maintain 5 V at the remote USB port connected after a long USB cables.
