3 Description

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 USB

2.0 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

VBUS, 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 VBUS 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.
