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
MIC2772
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.

supervisors that can be considered for replacement
