3 Description
The TPD2S703-Q1 is a 2-Channel Data Line Short-
to-Battery, Short-to-V_BUS, and IEC61000-4-2 ESD
protection device for automotive high-speed
interfaces like USB 2.0. The TPD2S703-Q1 contains
two data line nFET switches which ensure safe data
communication by providing best in class bandwidth
for minimal signal degradation while simultaneously
protecting the internal system circuits from any
overvoltage conditions at the VD+ and VD– pins. On
these pins, this device can handle overvoltage
protection up to 18-V DC. This provides sufficient
protection for shorting the data lines to the car battery
as well as the USB V_BUS rail. The overvoltage
protection circuit provides the most reliable short-to-
battery isolation in the industry, shutting off the data
switches in 200 ns and protecting the upstream
circuitry from harmful voltage and current spikes.
Additionally, the TPD2S703-Q1 only requires a single
power supply of 5 V in order to optimize power tree
size and cost. The OVP threshold and clamping
circuit can be adjusted by a resistor divider network to
provide a simple, cost effective way to optimize
system protection for any transceiver. The
TPD2S703-Q1 also includes a FLT pin which
provides an indication when the device sees an
overvoltage condition and automatically resets when
the overvoltage condition is removed.
The TPD2S703-Q1 also integrates system level IEC
61000-4-2 and ISO 10605 ESD clamps on the VD+
and VD– pins, thus eliminating the need for external
high voltage, low capacitance TVS clamp circuits in
the application.
