STEVAL-IFP006V1
High-side driver based on VNI4140K

This design demonstrates 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). The very low RDS(on) (only 80 mΩ typical @ 25 °C per channel) ensures very low power consumption during operation and, for this reason, makes the device an ideal solution for IP65 / IP67 requirements. The VNI4140K is compliant with IEC 61131-2 (Programmable Controllers International Standard).
