MIC2772
Transients on VCC
The MIC2772 is inherently immune to very short
“glitches” on VCC. In the case of very brief
transients, VCC may drop below the reset-voltage
threshold without triggering a reset. As shown in the
graph, the MIC2772 is relatively immune to
transients with typical duration of 25us. The lines on
the graph represent the typical allowable transient
duration for a given amount of threshold overdrive
that will not generate a reset. The data was taken by
adding negative-going square-wave pulse to a DC
input voltage set at 0.5V above actual measured
threshold for the part being characterized. Figure 1
shows the graph for the MIC2772[UP3] and Figure 2
shows the graph for the MIC2772[UP5]

Interfacing to Processors with Bi-directional
Reset Pins
Some microprocessors have reset signal pins that
are bi-directional, rather than input only. The
Motorola 68HC11 family is one example. Because
the MIC2772’s output is active-low, open-drain, it
can be connected directly to the processor’s reset
pin with only the pull-up resistor normally required.
MIC2772 Replaces Single Supervisor
The table below lists common single voltage
supervisors that can be considered for replacement
by MIC2772.
