max809 series, max810 series http://onsemi.com 7 applications information v cc transient rejection the max809 provides accurate v cc monitoring and reset timing during power?up, power?down, and brownout/sag conditions, and rejects negative?going transients (glitches) on the power supply line. figure 13 shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. any combination of duration and overdrive which lies under the curve will not generate a reset signal. combinations above the curve are detected as a brownout or power?down. typically, transient that goes 100 mv below the reset threshold and lasts 5.0 s or less will not cause a reset pulse. transient immunity can be improved by adding a capacitor in close proximity to the v cc pin of the max809. figure 13. maximum transient duration vs. overdrive for glitch rejection at 25 c duration v th overdrive v cc 10 250 200 110 60 maximum transient duration ( sec) 50 300 reset comparator overdrive (mv) 0 41 0 v th = 4.9 v 150 100 v th = 1.2 v 160 210 260 310 360 v th = 2.93 v reset signal integrity during power?down the max809 reset output is valid to v cc = 1.0 v. below this voltage the output becomes an ?open circuit? and does not sink current. this means cmos logic inputs to the microprocessor will be floating at an undetermined voltage. most digital systems are completely shutdown well above this voltage. however, in situations where reset must be maintained valid to v cc = 0 v, a pull?down resistor must be connected from reset to ground to discharge stray capacitances and hold the output low (figure 14). this resistor value, though not critical, should be chosen such that it does not appreciably load reset under normal operation (100 k will be suitable for most applications). v cc v cc reset r1 100 k max809/810 gnd figure 14. ensuring reset valid to v cc = 0 v reset processors with bidirectional i/o pins some microprocessor?s have bidirectional reset pins. depending on the current drive capability of the processor pin, an indeterminate logic level may result if there is a logic conflict. this can be avoided by adding a 4.7 k resistor in series with the output of the max809 (figure 15). if there are other components in the system which require a reset signal, they should be buffered so as not to load the reset line. if the other components are required to follow the reset i/o of the microprocessor, the buffer should be connected as shown with the solid line. v cc v cc microprocessor reset max809/810 gnd gnd 4.7 k figure 15. interfacing to bidirectional reset i/o reset v cc buffered reset to other system components buffer reset
