computers controllers intelligent instruments critical p power monitoring white goods networking telecommunications general description the max6701Cmax6708 microprocessor (p) supervisory circuits reduce the complexity and components required to monitor power-supply functions in p systems. these devices significantly improve system reliability and accu - racy compared to separate ics or discrete components. the max6701?max6708 family provides four func - tions: 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 max6701Cmax6708 family offers several pinout options to accommodate a variety of multivoltage micro - processor 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 inde - pendent 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 inde- pendent 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 . applications features small 8-pin sot23 package precision monitoring of +5.0v, +3.3v, +3.0v, +2.5v supply voltages 140ms reset timeout delay power-fail input with independent output; monitor inputs down to 0.62v (max6704?max6708) dual adjustable reset input for triple-voltage monitoring (max6701(a)/max6702(a)/max6703(a)) 1.6s watchdog timeout period (max6701(a)?max6707(a)) independent watchdog output (max6701(a)/max6702(a)/max6703(a)/ max6705(a)/max6706(a)/max6707(a)) manual reset input four reset output stage options active low push-pull (max6701(a), max6705(a)) active low open drain (max6703(a), max6707(a)) active high push-pull (max6702(a), max6706(a)) dual active low/high push-pull (max6704, max6708) guaranteed reset valid to v cc = 1v immune to short falling v cc transients low cost, few external components pin configurations continued at end of data sheet. ordering information continued at end of data sheet. insert the desired suffix letter (from the threshold suffix guide table) into the blank to complete the part number. all devices must be ordered in increments of 2500 pieces. sample stock is typically held on standard versions only. contact factory for availability. devices are available in both leaded and lead-free packaging. specify lead-free by replacing -t with +t when ordering. part temp range pin-package max6701 _ka-t -40c to +125c 8 sot23 max6701a_ka-t -40c to +125c 8 sot23 wdi rst_in2 rst_in1 ( ) are for max6702(a) only. 12 8 7 wdo reset (reset) v cc gnd mr sot23 top view 3 4 6 5 max6701(a)max6702(a) max6703(a) max6701-08/max6701a-03a/ max6705a-07a low-voltage, sot23 p supervisors with power-fail in/out, manual reset, and watchdog timer 19-1952; rev 4; 5/14 pin conigurations ordering information typical operating circuit and selector guide appear at end of data sheet. downloaded from: http:///

standard- vs. a-version comparison the max6701/max6702/max6703/max6705/max6706/ max6707s wdo latches low when one of the following events occurs: the watchdog timer times out (1.6s, typ). v cc , rst_in1, or rst_in2 is below its reset threshold. mr is pulled low. wdo only deasserts with a valid wdi transition. the max6701(a)/max6702(a)/max6703(a)/max6705(a)/ max6706(a)/ max6707(a)s wdo asserts when either v cc , rst_in1, or rst_in2 is below its reset thresh - old. wdo deasserts without a timeout delay when the undervoltage situation has expired. wdo is latched low when the watchdog timer elapses without seeing a wdi transition. wdo deasserts with a valid wdi transition or by pulling mr low. see figures 4 and 5 for standard-version timing. see figures 6 and 7 for a-version timing. watchdog timer the max6701 C max6707 watchdog circuit monitors the ps activity. if the p does not toggle the wdi within 1.6s, wdo goes low. when reset is asserted, the watchdog timer stays cleared and does not count. as soon as reset is released, the timer starts counting. wdo deasserts after a valid transition is detected at wdi. pulses as short as 50ns can be detected. typically, wdo is connected to the nmi input of a p. when v cc , rst_in1, or rst_in2 drop below the reset threshold, wdo goes low whether or not the watchdog timer has timed out. normally this would trigger an nmi, but reset goes low simultaneously, and thus overrides the nmi. the max6704 watchdog circuit does not have an inde - pendent watchdog output ( wdo ). if the p does not toggle the watchdog input within 1.6s, the max6704 asserts a reset output pulse for the reset timeout period. manual reset the manual reset input ( mr ) allows reset to be triggered by a pushbutton switch. the switch is effectively debounced by the reset pulse width. mr is cmos logic compatible, so it can be driven by an external logic line. mr can be used to force a watchdog timeout to generate a reset pulse in the max6701(a)/max6702(a)/ max6703(a)/max6705(a)/max6706(a)/max6707(a) by connecting wdo to mr . power-fail comparator the uncommitted power-fail comparator can be used for various purposes because its noninverting input and output are externally available. the inverting input is internally connected to a 0.62v reference. to build an early warning circuit for power failure, connect the pfi pin to a voltage-divider (see the typical operating circuit ). choose the voltage-divider ratio so that the voltage at pfi falls below 0.62v just before the regulator drops out. use pfo to interrupt the p so it can prepare for an orderly power-down. the low-input current at this pin allows for large resistor values in the divider. figure 6. max6701(a)/max6702(a)/max6703(a)/ max6705(a)/ max6706(a)/max6707(a) reset, mr, and wdo timing with wdi three-stated figure 5. max6701/max6702/max6703/max6705/max6706/ max6707 watchdog t rp t rp +5v 0v reset wdo +5v 0v mr t mr +5v 0v v cc v th v th t md t wd t wd +5v 0v wdi +5v 0v wdo +5v 0v reset +5v 0v (reset) t rp reset externally triggered by mr +5v 0v mr ( ) are for max6702/max6706 only. t wdi www.maximintegrated.com maxim integrated 8 max6701-08/max6701a-03a/ max6705a-07a low-voltage, sot23 p supervisors with power-fail in/out, manual reset, and watchdog timer downloaded from: http:///
reset input the max6701(a)/max6702(a)/max6703(a) include two adjustable reset inputs for monitoring up to a total of three system voltages (including v cc ). the thresholds for the monitored rst_in supplies are externally set with resistor-divider networks (figure 8). the reset output is asserted if any of the monitored supplies (v cc , rst_in1, or rst_in2) go below its specified threshold and remains asserted for the reset timeout period after all supplies are above their thresholds. applications information ensuring a valid reset output down to v cc = 0 when v cc falls below 1v, the max6701 C max6708 reset output no longer sinks current; it becomes an open circuit. high-impedance cmos logic inputs can drift to undetermined voltages if left undriven. if a pull- down resistor is added to the reset pin, as shown in figure 9, any stray charge or leakage currents are drained to ground, holding reset low. a resistor value (r1) is not critical; 100k is large enough not to load reset and small enough to pull reset to ground. this application works for push-pull output only (not for open-drain resets). monitoring other system voltages other systems can be monitored by connecting a voltage-divider to pfi and adjusting the ratio appropriately. in noisy systems, a capacitor between pfi and gnd reduces the power-fail circuits sensitivity to high- frequency noise on the line being monitored. reset can be asserted on other voltages in addition to the v cc supply line. connect pfo to mr to initiate a reset out- put pulse when pfi drops below 0.62v. figure 10 shows the max6704 C max6708 configured to assert a reset output when the secondary supply falls below the reset threshold. generating a reset from watchdog overlow connect wdo to mr to force a watchdog timeout to gen - erate a reset pulse for only the reset timeout period on the max6701(a)/max6702(a)/max6703(a)/max6705(a)/ max6706(a)/max6707(a). when the max6704 watch - dog times out, reset outputs are automatically asserted (no external connections required). for the max6701/ max6702/max6703/max6705/max6706/max6707 non-a versions, do not connect wdo to mr ; this creates a locked condition. figure 8. calculating adjustable voltage thresholds figure 7. max6701(a)/max6702(a)/max6703(a)/ max6705(a)/ max6706(a)/max6707(a) watchdog timing r1r2 0.62v pfi, rst_in1, or rst_in2 v external 0.62 r1 = r2 x ( v ext-th - 1 ) r2 v ext-th = ( 1 + r1 ) x 0.62v where v ext-th is the external voltage trip level. max6701(a)Cmax6708 t wd t wd t wd +5v 0v wdi +5v 0v wdo +5v 0v reset +5v 0v (reset) t rp +5v 0v mr ( ) are for max6702(a)/max6706(a) only. t wdi www.maximintegrated.com maxim integrated 9 max6701-08/max6701a-03a/ max6705a-07a low-voltage, sot23 p supervisors with power-fail in/out, manual reset, and watchdog timer downloaded from: http:///
