duration pulses versus RESET comparator over-
drive. As shown in the Maximum Transient
Duration vs. Reset Threshold Overdrive graph,
when the transient voltage becomes larger, the
time allowed before asserting a reset becomes

shorter (e.g., typically a transient of 100mV below
the reset threshold would have to be present for
more than 50µs to cause a reset). Immunity can be
increased by the addition of a small bypass capac-
itor of 0.1µF connected as closely to the V
possible.
