NCP300, NCP301
Voltage Detector Series
The NCP300 and NCP301 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 NCP300 series consists of complementary output devices that
are available with either an active high or active low reset output. The
NCP301 series has an open drain N-Channel output with either an
active high or active low reset output.
The NCP300 and NCP301 device series are available in the
Thin TSOP-5 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.
Machine Model Method 200 V.

NCP300 and NCP301 series are measured with a 10 pF capacitive load. NCP301 has an additional 470 k pull-up resistor con-
nected 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
DET+
is the sum of the lower detector threshold, V
DET-
plus the input hysteresis, V

OPERATING DESCRIPTION
The NCP300 and NCP301 series devices are second
generation ultra-low current voltage detectors. Figures 21
and 22 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+
), 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-
). 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
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 22 through Figure 29 shows various application
examples.

The above circuit combines an active high and an active low reset output device to form
a window detector for monitoring battery or power supply voltages. When the input
voltage falls outside of the window established by the upper and lower device
thresholds, the LED will turn on indicating a fault. As the input voltage falls within the
window, increasing from 1.0 V and exceeding the active low device's hysteresis
threshold, or decreasing from the peak towards 1.0 V and falling below the active high
device's undervoltage threshold, the LED will turn off. The device thresholds shown can
be used for a single cell lithium-ion battery charge detector.

Comparator hysteresis can be increased with the addition of
resistor R

do not account for the change of input current I

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 (V
DET-
+V
HYS
) is exceeded. Note that detector
thresholds (V
DET-
) that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
