EV-VND5T035AK
VND5T035AK evaluation board
Data brief

production data
Features
■
Simple single IC application board dedicated
for VND5T035AK-E
■
Provides thermal heat-sinking for ease of use
in prototyping
■
Provides electrical connectivity for easy
prototyping
Description
EV-VND5T035AK provides you an easy way to
connect ST’s surface mounted VIPower
®
drivers
into your existing prototype circuitry. This
evaluation board comes pre-assembled with
VND5T035AK-E high-side driver.
The VND5T035AK-E is monolithic device made
using STMicroelectronics
®
VIPower technology,
intended for driving resistive or inductive loads
with one side connected to ground. Active V
CC
pin
voltage clamp protects the device against low
energy spikes .
The device integrates an analog current sense
which delivers a current proportional to the load
current.
Fault conditions such as overload,
overtemperature or short to V
CC
are reported via
the current sense pin. Output current limitation
protects the device in overload conditions. The
device latches off in case of overload or thermal
shutdown.
The device is reset by a low level pass on the fault
reset standby pin.
A permanent low level on the inputs and on the
fault reset standby pins disables all outputs and
sets the device in standby mode.

Design recommendations EV-VND5T035AK
2/9 Doc ID 023987 Rev 2
1 Design recommendations
This evaluation board provides mounting solution and some heat sinking capability for
prototype development, but there are still external components that are required to make
these devices work in any application. For further information on how the evaluation board
has to be used you can refer to the AN4212 (see Appendix A: Reference documents).
Figure 2 illustrates the necessary components for any application.

ST has produced a user manual for safe designs using ST’s VIPower devices. This is
UM1557 (see Appendix A: Reference documents). UM1557 is a VIPower Hardware design
guide that provides all necessary information to successfully design your circuit using our
VIPower drivers.
All designs have different needs and requirements. Whatever design you decide to use, it
will still need to be verified in order to meet your application specifications. ST implies no
guarantee or warranty (see Appendix A: Reference documents).
