6-Pin µP Reset Circuit with  
Power-Fail Comparator  
General Description  
Features  
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.  
o Small 6-Pin SOT23 Package  
o Precision Factory-Set V Reset Thresholds  
CC  
Between 2.33V and 4.63V  
o Guaranteed RESET Valid to V  
= +1V  
CC  
The MAX6342–MAX6345 provide factory-trimmed V  
CC  
o 100ms min Reset Pulse Width  
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.  
o Debounced CMOS-Compatible Manual-Reset  
Input  
o Voltage Monitor for Power-Fail or Low-Battery

Note: The MAX6342–MAX6345 are available with factory-set  
reset thresholds from 2.33V to 4.63V (see Selector Guides 1, 2).
