Description
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. See Selector Guide for functions available.
