MAX6715A–MAX6729A/ MAX6797A
Dual/Triple, Ultra-Low-Voltage, SOT23 μP Supervisory Circuits
General Description
The MAX6715A–MAX6729A/MAX6797A are ultra-lowvoltage 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.
These devices monitor primary supply voltages (VCC1) from 1.8V to 5.0V and secondary supply voltages (VCC2) from 0.9V to 3.
