19-1867; Rev 1; 1/02 Dual Ultra-Low-Voltage SOT23 µP Supervisors with Manual Reset and Watchdog Timer General Description The MAX6826–MAX6831 are ultra-low-voltage microprocessor (µP) supervisory circuits designed to monitor two power supplies and have manual reset and watchdog input functions. These devices assert a system reset if any of the monitored supplies fall below the preprogrammed thresholds, and maintain reset for a minimum timeout period after the supplies rise above the threshold. Microprocessor supervisors significantly improve system reliability and accuracy compared to separate ICs or discrete components. These devices monitor primary voltages from +1.8V to +5.0V and secondary voltages from +0.9V to +2.5V.
