The need for hot insertion capability has dramatically increased
due to the demand of reducing system down time
and portability. The effect of hot insertion is an inrush current
or surge current which is produced when any uncharged
capacitors are connected to a power supply. The larger the
capacitors, the more energy is needed to charge them. Inrush
current can cause the voltage of the power supply to droop to
a level where system logic can be confused. This application
note describes one of the techniques to minimize the inrush
current to allow the user to utilize bulk capacitors of any size
for hot insertion applications. In addition, with this solution the
user does not have to wait for a long period of time between
multiple insertions.
