MAX706RESA+T

The MAX706P/R/S/T, MAX706AP/AR/AS/AT, and MAX708R/S/T microprocessor (µP) supervisory circuits reduce the complexity and number of components required to monitor +3V power-supply levels in +3V to +5V µP systems.
These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components.
The MAX706P/R/S/T and MAX706AP/AR/AS/AT supervi sory circuits provide the following four functions:1) A reset output during power-up, power-down, and brownout conditions.2) An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s.3) A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than the main supply.4) An active-low, manual-reset input
