The MAX6715–MAX6729 are ultra-low-voltage microprocessor (µP) supervisory circuits designed to monitor two or three system power-supply voltages. These devices assert a system reset if any monitored supply falls below its factory trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds.

The integrated dual/triple supervisory circuits significantly improve system reliability and reduce size compared to separate ICs or discrete components.
