TPD2S701-Q1 Automotive USB 2-Channel Data Line Short-to-V_BUS and IEC ESD Protection
1 Features
•1 AEC-Q100 Qualified
– –40°C to +125°C Operating Temperature
Range
• Short-to-VBUS Protection on VD+ and VD–
• ESD Performance VD+, VD–
– ±8-kV Contact Discharge (IEC 61000-4-2 and
ISO 10605 330 pF, 330 Ω)
– ±15-kV Air-Gap Discharge (IEC 61000-4-2 and
ISO 10605 330 pF, 330 Ω)
• High Speed Data Switches (1-GHz Bandwidth)
• Only Requires 5-V Power Supply
• Adjustable OVP Threshold
• Fast Overvoltage Response Time (200 ns typical)
• Thermal Shutdown Feature
• Integrated Input Enable and Fault Output Signal
• Flow-through Routing for Data Integrity
– 10-pin VSSOP Package (3 mm × 3 mm)
– 10-pin QFN Package (2.5 mm × 2.5 mm)
On these pins, this device can handle overvoltage
protection up to 7-V DC. This provides sufficient
protection for shorting the data lines to the USB V_BUS
rail. The overvoltage protection circuit provides the
most reliable short to V_BUS 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 TPD2S701-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
TPD2S701-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 TPD2S701-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.

3 Description
The TPD2S701-Q1 is a 2-Channel Data Line Short-
to-V_BUS and IEC61000-4-2 ESD protection device for
automotive high-speed interfaces like USB 2.0. The
TPD2S701-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.
