ncp304, ncp305 http://onsemi.com 16 operating description the ncp304 and ncp305 series devices are second generation ultra ? low current voltage detectors. figures 25 and 26 show a timing diagram and a typical application. initially consider that input voltage v in is at a nominal level and it is greater than the voltage detector upper threshold (v det+ ), and the reset output (pin 1) will be in the high state for active low devices, or in the low state for active high devices. if there is a power interruption and v in becomes significantly deficient, it will fall below the lower detector threshold (v det ? ). this sequence of events causes the reset output to be in the low state for active low devices, or in the high state for active high devices. after completion of the power interruption, v in will again return to its nominal level and become greater than the v det+ . the voltage detector has built ? in hysteresis to prevent erratic reset operation as the comparator threshold is crossed. although these device series are specifically designed for use as reset controllers in portable microprocessor based systems, they offer a cost ? effective solution in numerous applications where precise voltage monitoring is required. figure 26 through figure 32 shows various application examples. figure 25. timing waveforms v in v det + v det ? input voltage, pin 2 v in 0 v reset output (active low), pin 1 reset output (active high), pin 1 v in 0 v v det + v det ? v det + v det ?
