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.
http://onsemi.com
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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. This device series contains ESD protection and exceeds the following tests:
Human Body Model 2000 V per MIL−STD−883, Method 3015.

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, V
is the sum of the lower detector threshold, V
plus the input hysteresis, V
.

the comparator threshold is crossed.
Initially consider that input voltage V is at a nominal level

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.

significantly deficient, it will fall below the lower detector
threshold (V ). This sequence of events causes the Reset

NOTE: The ordering information lists standard undervoltage thresholds with active low outputs. Additional active low threshold devices, ranging
from 0.9 V to 4.9 V in 100 mV increments and NCP304 active high output devices, ranging from 0.9 V to 4.9 V in 100 mV increments
can be manufactured. Contact your ON Semiconductor representative for availability. The electrical characteristics of these additional
devices are shown in Tables 1 and 2.
