General Description
The MAX6342–MAX6345 family of microprocessor (P)
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 VCC
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, respectively. 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.
