STEVAL-IFP019V1 Demonstration Board

Quad high-side, smart-power, solid-state relay demonstration board based on the VNI4140K-32

STMicroelectronics' STEVAL-IFP019V1STMicroelectronics' 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 RDS(on)(only 80 mΩ typical at 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).

  • 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
  • Fast demagnetization of inductive loads
  • Protection against loss of ground
  • Current limitation
  • Undervoltage shutdown
  • Open drain diagnostic outputs
  • 3.3 V CMOS/TTL compatible inputs
  • Conforms to IEC 61131-2
  • RoHS compliant
