is that some internal circuits on the module (e.g. clock-generator chips) will generate
their own reset signals when the supply voltage exceeds a certain voltage threshold.
A voltage dip after passing this threshold may lead to these circuits becoming
confused resulting in a malfunction. It must be mentioned that this problem is quite
rare but has been observed in some mobile power supply applications. The best way
to ensure that this problem is not encountered is to observe the power supply rise
waveform through the use of an oscilloscope to determine if the rise is indeed
monotonic and does not have any dips. This should be done during the power supply
qualification phase therefore ensuring that the above mentioned problem doesn't
arise
