Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional peration of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to bsolute maximum rating conditions for extended periods may affect device reliability.




Description

The MAX6342MAX6345 family of microprocessor (P) upervisory circuits monitors power supplies in digital systems.

These devices significantly improve system reliability nd accuracy compared to separate ICs or discrete omponents.

The MAX6342MAX6345 provide factory-trimmed VCC eset threshold voltages from 2.33V to 4.63V and operate ith supply voltages between +1V and +5.5V. A +1.25V hreshold detector allows for a power-fail warning, for ow-battery detection, or for monitoring another powersupply. The MAX6342 contains an MR input and an ctive-low push-pull reset. The MAX6343 and MAX6344 re identical to the MAX6342 except they provide an ctive-low, open-drain reset and an active-high, pushpull eset, respectively. The MAX6345 provides a second eset output in place of the MR input to give it an activehigh ush-pull reset and an active-low push-pull reset.

MAX6342MAX6345 are packaged in a miniature 6-pinSOT23.
