NCP304, NCP305 Voltage Detector Series
The NCP304 and NCP305 series are second generation ultra-low current voltage detectors. These devices are specifically designed for use as reset controllers in portable microprocessor based systems where extended battery life is paramount. Each series features a highly accurate undervoltage detector with hysteresis which prevents erratic system reset operation as the comparator threshold is crossed. The NCP304 series consists of complementary output devices that are available with either an active high or active low reset output. The NCP305 series has an open drain N-Channel output with an active low reset output. The NCP304 and NCP305 device series are available in the SC-82AB package with standard undervoltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.

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 Vin is at a nominal level and it is greater than the voltage detector upper threshold (VDET+), 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 Vin becomes significantly deficient, it will fall below the lower detector threshold (VDET-). 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, Vin will again return to its nominal level and become greater than the VDET+. 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.

Comparator hysteresis can be increased with the addition of resistor RH. The hysteresis equations have been simplified and do not account for the change of input current Iin as Vin crosses the comparator threshold. The internal resistance, Rin is simply calculated using Iin = 0.26 mA at 2.6 V.

A simple voltage monitor can be constructed by connecting several voltage detectors as shown above. Each LED will sequentially turn on when the respective voltage detector threshold (VDET- +VHYS) is exceeded. Note that detector thresholds (VDET-) that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
