    Hello there,

    I am presently working on a energy harvesting circuit using RF source energy. I require a power management circuit which will allow me to deal with low levels of power obtained into my receiver circuit and charge a battery (for example a MEC - Microenergy cell).

    I am looking at the MAXIM17710 IC for the power management. I have looked at the datasheet, and but I can't seem to find exactly how much power the IC alone requires to operate. Below is the link to the datasheet. I would appreciate it if someone can lead me in the right direction.

    Regards

    It says in the datasheet, CHQ Quiescent Current, 625nA typical.

    Now I feel a little foolish for asking. So this is the minimum current required for the IC to perform its given task. Right.

    EDIT: So it doesn't require like a supply voltage source to operate like typical op-amps then?

    Thank you

    "a source as low as 0.75V" looks like your source needs to have atleast 0.75 volts to start with.
