3 Description

The TPD2S703-Q1 is a 2-Channel Data Line Short-

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

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.
