ATL432: IKA calculation

Umberto Frangi

Part Number: ATL432

Hi,

 can you add something in the datasheet to calculate and select proper values for Ika?

I found only the operating limit from 0.035 to 100mA.

Thanks

    Hi Umberto,

    The value of Ika is dependent on your load. At a minimum you want your ILoad + Imin to be less than the Imax.
    For example, if your load maximum will be 4mA and the Imin is 35uA then the total will be 4.035uA = Ik that will go through the device when the load is off, and you calculate your values based on that.

    I'll add this to the list of things for the next revision.
