Use LM5066 LM5064 to measure current?

Other Parts Discussed in Thread: LM5066, LM5064

Hi,

    I've seen it is said in datasheets of LM5066 and LM5064 that these parts feature (1). Real time monitoring of Vin, Vout, Iin, Pin Vaux with 12-bit resolution and 1kHz sampling rate (2). True input power averages dynamic power readings. I wonder can I read real time Iin from PMbus? I want to find a solution to measure the real time input current of my product. If LM5066 and 5064 can, how to get the current data?

    Thanks in advance.

    Hi,

    Yes the current, voltage and power telemetry data can be accessed from a PMBus communication bus on internal registers in the LM5066 or LM5064.  If you are only interested in telemetry, and not hot-swap capability, then you can use the LM5056 to get telemetery information across PMBus without the hot swap features.

    Let me know if this answers your question.

    Regards,
