19-1868; Rev 1; 1/01 Low-Voltage SOT23 µP Supervisors with Manual Reset and Watchdog Timer General Description 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 VCC rises above the threshold.
In addition, a watchdog timer monitors against code execution errors.
