STEVAL-IFP019V1 Quad high-side smart-power solid-state relay demonstration board based on the VNI4140K-32 Data brief Features Output current: 1 A per channel Shorted load protections Junction overtemperature protection Case overtemperature protection for thermal independence of the channels Thermal case shutdown non-simultaneous restart for the various channels Protection against loss of ground Current limitation Undervoltage shutdown Open drain diagnostic outputs 3.3 V CMOS/TTL compatible inputs Fast demagnetization of inductive loads Conforms to IEC 61131-2 RoHS compliant 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 (only DS(on) 80 m 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).
