STEVAL-IFP005V2
■
Program selector (U2)
■
ICC connector for software adjustment
■
Free development area with hole matrix
available for application breadboard adaptation
The purpose of this design is to demonstrate the
features of the VN751PT high-side driver.
■
Overvoltage protection is not implemented on
the board but some solder pads are available
to implement it in two different ways:
The application offers robustness and complies
with EMC industrial standards.
■
Varistor addition between mains voltage
■
Transil addition between TRIAC A2-G
terminals
■
RoHS compliant
Description
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 RDSon (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).
