Voltage Detector Series  
with Programmable Delay  
The NCP302 and NCP303 series are second generation ultra−low  
current voltage detectors that contain a programmable time delay  
generator. 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 and an externally programmable time delay generator. This  
combination of features prevents erratic system reset operation.  
The NCP302 series consists of complementary output devices that  
are available with either an active high or active low reset. The  
NCP303 series has an open drain N−Channel output with an active low  
reset output.

NCP302 and NCP303 series are measured with a 10 pF capacitive load. NCP303 has an additional 470 k pullup resistor  
connected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low ‘L’ devices. Output  
time delay t and t are dependent upon the delay capacitance. Refer to Figures 30, 31, and 32. The upper detector

plus the input hysteresis, V

OPERATING DESCRIPTION

DET+  
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  
N−Channel MOSFET and allow pullup resistor R to charge  
external capacitor C , 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  
in  
nominal level and it is greater than the voltage detector upper  
the reset output will revert back to its original state. The reset  
output time delay versus capacitance is shown in Figures 12  
through 14. 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 45 show various  
application examples.

D
will be at the same level as V , 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  
in  
and V becomes significantly deficient, it will fall below the  
in  
lower detector threshold (V  
delay capacitor C 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,

Figure 46. Multi−Rail Supply Undervoltage Monitor with Power Good  
This circuit monitors multiple power supply rails for  
undervoltage conditions. If any of the three power supplies  
are in an undervoltage condition, the NCP302 reset output  
will be immediately set to an active low level. All three  
power supplies must be above their minimum voltage levels  
for the NCP302 reset output to generate a “Power Good”  
approximately equal to 1.0 MW, and R1 > 5 kW. If R1 << R ,  
D
then R1 also can decrease the reset output delay time (t  
variance over the operating temperature range.  
)

The Power Good signal time delay (t ) can be estimated

by: t R * C , with R in Ohms, and C in Farads. If
