adm803/adm809/adm810 data sheet rev. i | page 8 of 11 interfacing to other devices the adm803 / adm809 / adm810 series is designed to integrate with as many devices as possible and, therefore, has a standard output dependent on v cc . this enables the parts to be used in both 3 v and 5 v, or any nominal voltage within the minimum and maximum specifications for v cc . this design simplifies interfacing the adm803 / adm809 / adm810 to other devices. ensuring a valid reset output down to v cc = 0 v when v cc falls below 0.8 v, the adm803 / adm809 reset no longer sinks current. a high impedance cmos logic input connected to reset may, therefore, drift to undetermined logic levels. to eliminate this problem, a 100 k resistor should be connected from reset to ground. figure 12. ensuring a valid reset output down to v cc = 0 v benefits of an accurate reset threshold in other microprocessors, tolerances in supply voltages lead to an overall increase in reset tolerance levels due to the deterioration of the reset circuits power supply. in the adm803 / adm809 / adm810 , the possibility of a malfunction during a power failure is greatly reduced because the devices can operate effectively even when there are large degradations of the supply voltages. another advantage is the very accurate internal voltage reference circuit of the adm803 / adm809 / adm810 . these benefits combine to produce an exceptionally reliable voltage monitor circuit. interfacing to microprocessors with multiple interrupts in a number of cases, it is necessary to interface many interrupts from different devices (for example, thermal, altitude, and velocity sensors). the adm803 / adm809 / adm810 can easily be integrated into existing interrupt-handling circuits, as shown in figure 13, or can be used as standalone devices. figure 13. interfacing to microprocessors with multiple interrupts gnd adm809 v cc v cc reset 03736-011 4-line bcd to microprocessor adm809 gnd v cc v cc reset other sensing devices priority encoder 74ls147 03736-012
