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.

These devices monitor primary supply voltages (VCC1) from 1.8V to 5.0V and secondary supply voltages (VCC2) from 0.9V to 3.3V with factory-trimmed reset threshold voltage options (see the Reset Voltage Threshold Suffix Guide in the full data sheet). An externally adjustable RSTIN input option allows customers to monitor a third supply voltage down to 0.62V. These devices are guaranteed to be in the correct reset output logic state when either VCC1 or VCC2 remains greater than 0.8V.

A variety of push-pull or open-drain reset outputs along with watchdog input, manual-reset input, and power-fail input/output features are available (see the Selector Guide in the full data sheet). Select reset timeout periods from 1.1ms to 1120ms (min) (see the Reset Timeout Period Suffix Guide in the full data sheet). The MAX6715A–MAX6729A/MAX6797A are available in small 5-, 6-, and 8-pin SOT23 packages and operate over the -40°C to +125°C temperature range.
