STEVAL-IFP006V1评估板是建立于芯片VNI4140K之上的。该板的目的是为了展示VNI4140K四高侧智能功率固态继电器的功能。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 RDS(on) (only 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).
