The need for hot insertion capability has dramatically increaseddue to the demand of reducing system down timeand portability. The effect of hot insertion is an inrush currentor surge current which is produced when any unchargedcapacitors are connected to a power supply. The larger thecapacitors, the more energy is needed to charge them. Inrushcurrent can cause the voltage of the power supply to droop toa level where system logic can be confused. This applicationnote describes one of the techniques to minimize the inrushcurrent to allow the user to utilize bulk capacitors of any sizefor hot insertion applications. In addition, with this solution theuser does not have to wait for a long period of time betweenmultiple insertions.
