General Description
The MAX6342–MAX6345 family of microprocessor (μP)
supervisory circuits monitors power supplies in digital sys-
tems. These devices significantly improve system reliabili-
ty and accuracy compared to separate ICs or discrete
components.
The MAX6342–MAX6345 provide factory-trimmed V
CC
reset threshold voltages from 2.33V to 4.63V and operate
with supply voltages between +1V and +5.5V. A +1.25V
threshold detector allows for a power-fail warning, for low-
battery detection, or for monitoring another power supply.
The MAX6342 contains an
MR
input and an active-low
push-pull reset. The MAX6343 and MAX6344 are identical
to the MAX6342 except they provide an active-low, open-
drain reset and an active-high, push-pull reset, respective-
ly. The MAX6345 provides a second reset output in place
of the
MR
input to give it an active-high push-pull reset
and an active-low push-pull reset.
All of the devices are packaged in a miniature 6-pin
SOT23.
