TMSDC6727BGDHA250

General Description
The MAX6715A–MAX6729A/MAX6797A 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.
