3 Description
The TPD3S714-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, rear seat entertainment, 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 GHz allows for a
clean USB2.0 high-speed (480 Mbps) eye diagram
which helps pass stringent USB certification tests 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 over-voltage conditions at
the V_{BUS_CON}, VD+, and VD- pins. On these pins, the
TPD3S714-Q1 can handle over-voltages up to 18 V
for hot plug and DC events. The over-voltage
protection circuit provides the most reliable short-to-
battery isolation in the industry, shutting off the
switches and protecting the upstream transceiver
from harmful voltage and current spikes. The
V_{BUS_CON} pin also provides an accurate current
limited load switch up to 0.5 A. The leading over-
current protection automatically limits current to
prevent drooping of the upstream rail during short-to-
ground events. Additionally, this device also
integrates system level IEC 61000-4-2 and ISO
10605 ESD protection on V_{BUS_CON}, VD+, and VD-
pins which removes the need to provide external
high-voltage, low capacitance ESD diodes
