STEVAL-IFP005V2
Description
The purpose of this design is to demonstrate the
features of the VN751PT high-side driver.
The application offers robustness and complies
with EMC industrial standards.
It implements short-circuit/overload protection
and thermal management as well, achieving best
in class MTBF values.
The reference design is suitable for use in
programmable logic controllers (PLCs) as well as
to drive generic loads which require up to 2.5 A of
nominal current (the typical current limitation is
4.5 - 5 A).
Thanks to the very low R_DSon (only 60 mΩ Typ. @
25 °C) the device allows very low power
consumption during the operation and for this
reason it represent an ideal solution for IP65 /
IP67 requirements. The device is compliant with
IEC 61131-2 (programmable controllers
international standard).
