Voltage Detector Series
NCP304, NCP305
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.

4. In the case of CMOS Output Type: The time interval between the rising edge of VDD input pulse from 0.7 V to (+VDET) +2.0 V and output
voltage level becoming to VDD/2. In the case of N−Channel Open Drain Output Type: Output pin is pulled up with a resistance of 470 kW
to 5.0 V, the time interval between the rising edge of VDD input pulse from 0.7 V to (+VDET) +2.0 V and output voltage level becoming to
2.5 V.

NCP304 and NCP305 series are measured with a 10 pF capacitive load. NCP305 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. The upper detector
threshold, VDET+ is the sum of the lower detector threshold, VDET− plus the input hysteresis, VHYS.

OPERATING DESCRIPTION
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.
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
“L” in Part Name
“H” in Part Name

Comparator hysteresis can be increased with the addition of

do not account for the change of input current Iin as Vin crosses

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.
