Overview

The MAX6701—MAX6708 microprocessor (μP) supervisory circuits reduce the complexity and components required to monitor power-supply functions in μP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX6701—MAX6708 family provides four functions: a reset output during power-up, power-down, and brownout conditions; an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s; a 0.62V threshold detector for power-fail warning; and an active-low manual reset input. The MAX6701—MAX6708 family offers several pinout options to accommodate a variety of multivoltage microprocessor supervision applications. The MAX6701(A)/MAX6702(A)/MAX6703(A) monitor three supply voltages (one fixed threshold and two adjustable) to drive a single reset output and include a manual reset input and a watchdog timer with an independent output. The MAX6704 monitors a single-supply voltage to drive complementary reset outputs and includes an independent adjustable power-fail-in/power-fail-out comparator, a manual reset input, and a reset-based watchdog timer. The MAX6705(A)/MAX6706(A)/MAX6707(A) monitor a single-supply voltage to drive a single reset output and include an independent adjustable power-fail-in/power-fail-out comparator, a manual reset input, and a watchdog timer with an independent output. The MAX6708 is the same as the MAX6704 but without the watchdog timer function. See the Detailed Description for differences between non-A and A versions.
