Description

General part information

MAX6831 Series

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. These devices are guaranteed to be in the correct state for VCCdown to +1.0V.A variety of preprogrammed reset threshold voltages are available (see the Threshold Suffix Guide). The devices include manual reset and watchdog inputs. The MAX6829/MAX6830/MAX6831 provide a factory-trimmed threshold to monitor a 2nd voltage down to +0.9V. The MAX6826/MAX6829 have a push-pull active-low RESET, the MAX6827/MAX6830 have a push-pull RESET and the MAX6828/MAX6831 have an open-drain active-low RESET. The MAX6826/MAX6827/MAX6828 have an auxiliary monitor that allows user adjustable input to monitor voltages down to +0.6V.
