19-1952; Rev 3; 12/05 Low-Voltage, SOT23 µP Supervisors with Power- Fail In/Out, Manual Reset, and Watchdog Timer MAX6701­08/MAX6701A­03A/05A­07A General Description Features The MAX6701­MAX6708 microprocessor (µP) supervisory Small 8-Pin SOT23 Package circuits reduce the complexity and components required Precision Monitoring of +5.0V, +3.3V, +3.0V, +2.5V to monitor power-supply functions in µP systems. These Supply Voltages devices significantly improve system reliability and accu- 140ms Reset Timeout Delay racy compared to separate ICs or discrete components. Power-Fail Input with Independent Output; The MAX6701­MAX6708 family provides four functions: Monitor Inputs Down to 0.62V (MAX6704­MAX6708) a reset output during power-up, power-down, and Dual Adjustable Reset Input for Triple-Voltage brownout conditions; an independent watchdog output Monitoring (MAX6701(A)/MAX6702(A)/MAX6703(A)) that goes low if the watchdog input has not been toggled 1.6s Watchdog Timeout Period within 1.6s; a 0.62V threshold detector for power-fail (MAX6701(A)­MAX6707(A)) warning; and an active-low manual reset input. Independent Watchdog Output The MAX6701­MAX6708 family offers several pinout (MAX6701(A)/MAX6702(A)/MAX6703(A)/ options to accommodate a variety of multivoltage micro- MAX6705(A)/MAX6706(A)/MAX6707(A)) processor supervision applications. Manual Reset Input The MAX6701(A)/MAX6702(A)/MAX6703(A) monitor Four Reset Output Stage Options three supply voltages (one fixed threshold and two Active Low Push-Pull (MAX6701(A), MAX6705(A)) adjustable) to drive a single reset output and include a Active Low Open Drain (MAX6703(A), MAX6707(A)) manual reset input and a watchdog timer with an inde- Active High Push-Pull (MAX6702(A), MAX6706(A)) pendent output. The MAX6704 monitors a single-supply Dual Active Low/High Push-Pull (MAX6704, voltage to drive complementary reset outputs and MAX6708) includes an independent adjustable power-fail-in/power- Guaranteed Reset Valid to VCC = 1V fail-out comparator, a manual reset input, and a reset- Immune to Short Falling V based watchdog timer. The MAX6705(A)/MAX6706(A)/ CC Transients MAX6707(A) monitor a single-supply voltage to drive a Low Cost, Few External Components single reset output and include an independent
