    Hi Abhijeet Godbole,

    The idea is to make current sink floating that don’t use or need the Voltage power from the Current sink pin, because when I sinking from the I/O the voltage get below the voltage that the ICS need or working (below 2.5v) then I don’t get the current I want, that mean if the voltage is above 2.5v it give the current I want (300uA) but below 2.5v is not give the current I want.

    Do you have any idea how to fix this problem?

    Thanks,

    Shlomi
