    Single and Polyphase Power Management IC

    Please recommend me any IC for measuring Single and Three phase power measurements.

    That is, MSP430F6779 and ADE7868 they are only Polyphase IC..

    But I need IC work for both Single and Three Phase System.

    Re: Single and Polyphase Power Management IC

    Hi,

    1) Did you read the datasheets? Are you sure the 3-phase ones can't be used for single phase?

    2) You surely are free to use 3 x single phase ones and combine the data with software

    Yes I am sure and read that Polyphase IC not recommended for Single phase but it can use for 2 phase.

    Re: Single and Polyphase Power Management IC

    Hi,

    Out of curiosity I tried to find out why AD7686 can not be used in single phase mode by going through the datasheet.
    I could not find such informations.

    Where did you find it?

    Re: Single and Polyphase Power Management IC

    I am talking about ADE7868 not AD7868.

    Re: Single and Polyphase Power Management IC

    Hi,

    Sorry, my fault. I also meant ADE7868.

    Still I don´t find the information that it´s not possible to use it in single phase application.

    Re: Single and Polyphase Power Management IC

    No problem.

    I sent a email to "Analog Devices" for asking about single phase version of ADE7878.

    ADE7878 is a latest version of ADE7868.

    Please let me know that do you know how to interface with MCU?, I know, but I need some guidance.

    Re: Single and Polyphase Power Management IC

    ADE7878 is a latest version of ADE7868.
    ADE7878 is not recommended for new designs, ADE7878A ist the recent type.

    I agree with KlausST. You need a poly phase energy meter IC to support 3-phase measurement, there's no reason why it can't work for single phase as well.

    Available interface is SPI or I2C.

    Re: Single and Polyphase Power Management IC

    Thank you for correction i.e ADE7878A.

    Ok, but same family IC for single phase is available.
    For single phase, we can use it.ADE7753
