Hi,

How to calculate the Power-ON surge current of a IC. . Shall i take
the maximum current as Power-ON surge ? But normally this Inrush
Current will be higher than the Maximum current of the operating
current IC

This sounds like a myth to me. I can't imagine why a chip would draw
more current than the current stated in the absolute maximum ratings.

It is possible for a chip to draw more current than specified due to
latch-up. If this is the case, there is probably an error in the
design.
