Description
The STEVAL-IFP019V1 demonstration board
shows the features of the VNI4140K-32 quad
high-side smart-power solid-state relay.
The application offers robustness and complies
with EMC industrial standards. It implements
short-circuit/overload protection and also thermal
management, 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 1 A of
nominal current (the typical current limitation is
1.1 - 2.6 A). Thanks to the very low R_DS(on) (only
80 mΩ typical @ 25 °C per channel) the device
allows very low power consumption during
operation and for this reason it offers an ideal
solution for IP65 / IP67 requirements. The
VNI4140K-32 is compliant with IEC 61131-2
(international standard for programmable
controllers).
