Description

General part information

MAX6822 Series

The MAX6821—MAX6825 are low-voltage microprocessor (µP) supervisory circuits that combine voltage monitoring, watchdog timer, and manual reset input functions in a 5-pin SOT23 package. Microprocessor supervisory circuits significantly improve system reliability and accuracy compared to separate ICs or discrete components. These devices assert a reset signal whenever the monitored voltage drops below its preset threshold, keeping it asserted for a minimum timeout period after VCCrises above the threshold. In addition, a watchdog timer monitors against code execution errors. A debounced manual reset is also available. The MAX6821—MAX6825 monitor voltages from +1.8V to +5.0V. These outputs are guaranteed to be in the correct state for VCCdown to +1.0V.Nine preprogrammed reset threshold voltages are available (see theThreshold Suffix Guide). The MAX6821, MAX6822, and MAX6823 all have a manual reset input and a watchdog timer. The MAX6821 has push-pull RESET, the MAX6822 has open-drain active-low RESET, and the MAX6823 has push-pull active-low RESET. The MAX6824 has a watchdog timer and both push-pull active-low RESET and push-pull RESET. The MAX6825 has a manual reset input and both push-pull active-low RESET and push-pull RESET.
