STEVAL-IFP006V1
using the VNI4140K
Data Brief
STEVAL-IFP006V1
Description
The purpose of this design is to demonstrate the
features of the VNI4140K 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 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 0.7 A of
nominal current (the typical current limitation is
0.7 - 1.7 A). Thanks to the very low R
80 mΩ typ. @ 25 °C per channel) the device
allows very low power consumption during
operation and for this reason making it an ideal
solution for IP65 / IP67 requirements. The device
is compliant with IEC 61131-2 (Programmable
Controllers International Standard).

STEVAL-IFP006V1 Connectors
2 Connectors
This evaluation board uses two input header connectors, one screw drives the four-channels
output connector and one screw drives the two-channel supply connector.
Both input connectors, J5 and J1, provide the same bidirectional evaluation board
signalization guaranteeing the maximum compatibility with existing ST tools, such as the
ST7540 FSK powerline transceiver evaluation board (see AN2451 ) and similar.
