ncp302, ncp303 http://onsemi.com 16 operating description the ncp302 and ncp303 series devices consist of a precision voltage detector that drives a time delay generator. figures 37 and 38 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+ ). the voltage at pin 5 and capacitor c d will be at the same level as v in , 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 ? ) and the external time delay capacitor c d will be immediately discharged by an internal n ? channel mosfet that connects to pin 5. 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 will turn off the n ? channel mosfet and allow pullup resistor r d to charge external capacitor c d , thus creating a programmable delay for releasing the reset signal. when the voltage at pin 5 exceeds the inverter/buffer threshold, typically 0.675 v in , the reset output will revert back to its original state. the reset output time delay versus capacitance is shown in figures 30 through 32. the voltage detector and inverter/buffer have built ? in hysteresis to prevent erratic reset operation. 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 and time delay are required. figures 38 through 46 show various application examples. figure 37. timing waveforms t d2 v in v det + v det ? input voltage, pin 2 capacitor, pin 5 v in 0 v reset output (active low), pin 1 v in reset output (active high), pin 1 v in 0 v 0.675 v in v det ? v det ?
