Overview
19-1568; Rev 2; 12/05 6-Pin µP Reset Circuit with Power-Fail Comparator 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, pushpull reset, respectively.
The MAX6345 provides a second reset output in place of the MR input to give it an activehigh push-pull reset and an active-low push-pull reset.
All of the devices are packaged in a miniature 6-pin SOT23.
