Maxim Integrated MAX6827
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. These devices monitor primary voltages from +1.8V to +5.0V and secondary voltages from +0.9V to +2.5V.| Part No. | MAX6827 |

GENERAL DESCRIPTION
Microprocessor supervisors significantly improve system reliability and accuracy compared to separate ICs or discrete components. These devices are guaranteed to be in the correct state for VCC down to +1.0V. A variety of preprogrammed reset threshold voltages are available (see Threshold Suffix Guide). The devices include manual reset and watchdog inputs. The MAX6829/MAX6830/MAX6831 provide a factorytrimmed threshold to monitor a 2nd voltage down to +0.9V. The MAX6826/MAX6829 have a push-pull RESET , the MAX6827/MAX6830 have a push-pull RESET and the MAX6828/MAX6831 have an open-drain RESET. The MAX6826/MAX6827/MAX6828 have an auxiliary monitor that allows user adjustable input to monitor voltages down to +0.6V. See Selector Guide for functions available.FEATURES
