Introduction

Introduction
Texas Instrument’s TPD2S701-Q1 evaluation module helps designers evaluate the operation and
performance of the TPD2S701-Q1 device. The TPD2S701-Q1 contains two data line nFET switches which
ensure safe data communication while protecting the internal system circuits from any over-voltage
conditions at the VD+ and VD– pins. See Figure 1. On these pins, this device can handle over-voltage
protection up to 18-V DC. This provides sufficient protection for shorting the data lines to the car battery
as well as the USB VBUS rail. This EVM allows the user to evaluate the operation of this device in a passthrough application, as well as to measure the ESD response and bandwidth of the device. In addition,
this EVM offer, contains the device in both the DSK and DGS package offering, so that the device can be
evaluated regardless of the preferred package option.
Figure 1. TPD2S701-Q1 EVM

Board Setup
The TPD2S701-Q1 EVM consists of 5 devices allowing for three different test setups.
2.1
Device Information
To power the EVM, apply 5 V to the pin labeled '+5V' on the EVM. If the user is testing a device in Mode
0, they will need to apply an additional voltage to the pin labeled 'Vref', but if testing is done in Mode 1
then the 'Vref' pin can be left unused. The functional devices modes are discussed in greater depth later,
but for detailed information see the device data sheet.
Each TPD2S701-Q1 in this EVM contains headers for enabling the device and a mode switch to enable
each mode of operation. Before using any of the devices, ensure that the particular device has a header
between the center pin and the pin labeled 'On' for the corresponding set of pins. It is recommended that
any devices not currently in use be disabled by moving the header between the center pin and the 'Off'
pin.
In addition, the EVM allows testing of each device in either functional mode 0 or functional mode 1 by
moving the switch corresponding to the device. The functional mode changes how the overvoltage set
point of the TPD2S701-Q1 is determined. In order to operate properly, the device must be power-cycled
when changing functional modes. We recommend only changing device modes while there is no power
applied to the '+5V' board power to ensure that the device works properly.
In functional mode 0 the overvoltage set point is determined by an external voltage applied to the 'Vref' pin
on the EVM. The correlation between the Vref voltage and the overvoltage set point is determined by a
formula that can be found in the device datasheet. The voltage applied to the 'Vref' pin applies to all
TPD2S701-Q1 devices on the EVM that are currently enabled and in mode 0.

Board Setup

If the switch is placed in position 1, the overvoltage set point is determined instead by external resistors
and an internal voltage reference. In this mode, the device can operate with no external voltage applied to
the 'Vref' pin. The EVM is designed with external resistors to always have a 3.6 V overvoltage set point in
mode 1.
Each device also contains a yellow test point that allows the user to measure the corresponding devices
FLT output. Measure the voltage on this pin to record when the device goes into an undervoltage,
overvoltage, or thermal shutdown state to ensure that the device operates as expected.
2.2
Passthrough Evaluation
Devices U1 and U2 are in a configured to allow for USB 2.0 pass-through testing. The two devices are in
a DSK and DGS package respectively, but otherwise are functionality identical. Each has a male and
female USB port that can be plugged into any system with a USB 2.0 port to ensure that the device can
protect existing systems. Plug J9 or J13 into a USB port and then plug a peripheral into J10 or J14 to
ensure that during typical operation the TPD2S701-Q1 has no effect on standard USB operations. While
plugged in, use a probe to apply a voltage above the overvoltage setpoint to one of the data lines and
observe that the TPD2S701-Q1 isolates the system, preventing any data pass-through. After the voltage is
removed, the TPD2S701-Q1 must remove the isolation and quickly re-allow data communications. See
Figure 2.
By taking advantage of this pass-through evaluation, the user can quickly determine whether the
TPD2S701-Q1 is optimal for their existing system without requiring any board changes or non-optimal test
setups. There is an additional USB 2.0 pass-through setup at the bottom of the board that is designed for
calibration. The board and trace add some parasitics and bandwidth loss that do not reflect how the
TPD2S701-Q1 operates when designed into a system. This additional pass-through allows for calibration
to account for those and get a more accurate picture of the TPD2S701-Q1.

Bandwidth Evaluation
Devices U3 and U4 are configured to allow for precise bandwidth measurements. The two devices are in a
DSK and DGS package respectively, but otherwise are functionally identical. Each device has SMA
connectors on both the connector and system side of the USB 2.0 Data line pins that offer a low
attenuation way to connect a network analyzer and ensure that during typical operation the TPD2S701-Q1
capacitance and inductance do not impede signal speed past where the maximum line signal speed is. In
addition, when U3 and U4 are placed into a fault state the bandwidth can be measured to ensure that the
DC fault voltage is significantly attenuated. See Figure 3.
There is an additional bandwidth setup that is designed for calibration. The board and trace add some
parasitics and bandwidth loss that do not reflect how the TPD2S701-Q1 operates when designed into a
system. This additional pass-through allows for calibration to account for those and get a more accurate
picture of the bandwidth of the TPD2S701-Q1.
Figure 3. Bandwidth Evaluation Configuration
2.4
IEC ESD Evaluation
Device U5 is configured to be an optimal place to test the TPD2S701-Q1 IEC ESD strike response. This
configuration contains the TPD2S701-Q1 in only the DSK package as there is no difference in the
performance between the DSK and DGS packages. Test points VD+ and VD– offer strike points that can
targeted with an external ESD simulator on the protected data lines. By measuring with attenuated scope
probes on the SMB connecters labeled D+ and D– during an ESD strike, the user can capture a waveform
of what the protected system is exposed to during an ESD strike. Resistors R7 and R9 are 150-Ω resistors
in series with the ESD pulse to provide a 4x attenuation with the 50-Ω oscilloscope probe impedance. In
addition to this, to ensure that the oscilloscope is not harmed a 10x attenuation probe must be used. See
Figure 4.
For more information about Texas Instruments recommended ESD test setup, see the application report,
IEC 61000-4-x Tests for TI’s Protection Devices.

d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le
présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le
manuel d’usage et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne
non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de
l'émetteur
