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 m
Ω 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).
