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

The MAX814/MAX815/MAX816 are high-accuracy microprocessor (P) supervisory circuits that provide power-on reset, watchdog, and power-fail functions. MAX814 eliminate manual trimming and improve reliability in critical  pplications needing high-accuracy reset thresholds. The RESET output of MAX814 is guaranteed to be in the correct state for Vcc down to 1V. The reset comparator is designed to ignore fast transients on Vcc. Reset thresholds are available for operation with a variety of 3V and 5V supply voltages.

A 75A maximum supply current makes the MAX814/ MAX815/MAX816 ideal for use in portable equipment. All three devices are available in 8-pin DIP and SO packages. See the Selector Table below for a review of features.
