output channel provides enhanced diagnostic
functions including fast detection of overload and
short-circuit to ground through power limitation
indication, overtemperature indication, shortcircuit to VCC diagnosis and ON-state and
OFF-state open-load detection.
The current sensing and diagnostic feedback of
the whole device can be disabled by pulling the
CS_DIS pin high to share the external sense
resistor with similar devices.

Device summary
Description
EV-VND5E025AK 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
VND5E025AK-E high-side driver.
The VND5E025AK-E is a double channel
high-side driver manufactured using ST
proprietary VIPower M0-5 technology and housed
in PowerSSO-24 package. The VND5E025AK-E
is designed to drive 12 V automotive grounded
loads, providing protection, diagnostics and easy
3 V and 5 V CMOS-compatible interface with any
microcontroller.
The device integrates advanced protective
functions such as load current limitation, inrush
and overload active management by power
limitation, overtemperature shut-off with autorestart and overvoltage active clamp. A dedicated

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
UM1556 (see Appendix A: Reference documents). UM1556 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).
