    Multifunction relay integrated circuits and reference designs


    Our integrated circuits and reference designs help you design multifunction relays with protection, monitoring and diagnostics features integrating data acquisition, signal processing, protection algorithms, high- or low-speed communication, isolation and HMI functionalities.

    Innovative and highly integrated multifunction relays often require:

    • Accurate measurement of AC current and voltage inputs over a wide range.
    • Communication interfaces, including Ethernet copper/fiber 10/100/1000, USB and RS485.
    • Efficient DC supply using DC/DC converters with an integrated inductor and onboard power management.
    • HMI solutions for LCDs for graphic display and LEDs for diagnostics and status indication.
