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.

NCP300 and NCP301 series are measured with a 10 pF capacitive load. NCP301 has an additional 470 k pull−up 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
The NCP300 and NCP301 series devices are second
generation ultra−low current voltage detectors. Figures 20
and 21 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
Input Voltage, Pin 2
Reset Output (Active Low), Pin 1
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 33 shows various application
examples.

VCC TRANSIENT REJECTION
The NCP300 and NCP301 series provides accurate VCC
monitoring and reset timing during power−up,
power−down, and brownout/sag conditions, and rejects
negative glitches on the power supply line. Figure 22 shows
the maximum transient duration vs. maximum negative
excursion (overdrive) for glitch rejection. Any combination
of duration and overdrive which lies under the curve will not
generate a reset signal. A below−VCC condition (on the
right) is detected as a brownout or power−down. Typically,
any transient that goes 100 mV below the reset threshold and
lasts 5.0 ms or less will not cause a reset pulse.
Transient immunity can be improved by adding a
capacitor in close proximity to the VCC pin of the NCP30x.
FACTORS TO BE CONSIDERED FOR VOLTAGE
OPTION SELECTION
The following hysteresis graph depicts VDET−_min/max
and VDET+_min/max for an active low Reset device:

Figure 24.
For selecting a voltage option in the NCP30X family,
three major factors should be considered:
1. VDET+_max: Maximum detector threshold voltage
for increasing Vin for the NCP30X device.
2. Vin_min: Minimum voltage output of the power
supply. This is also the input voltage to the
NCP30X device.
3. VCC_min: Minimum power supply voltage
specification for the device that is protected by the
NCP30X.
The VDET+_max for an NCP30X device is normally
calculated as follows:

Where:
VDET−_max = Maximum detector threshold voltage for
decreasing Vin
VHYS_max = Maximum detector threshold hysteresis
The above two parameters can be obtained directly from
the data sheet to figure out the VDET+_max.
In the NCP30X family, for a given VDET−_typ, which is the
typical detection voltage reflected in the part number, the
threshold values are designed to the following targets (at
25°C):

(eq. 7)
NCP300, NCP301
PROPAGATION DELAY VARIATION
On the other hand (see above paragraph), a minimum
overdrive value from Vthreshold to VCC must be respected.
That means Vin (minimum value of VCC) must be higher
enough than VDET+ (VDET− + hysteresis) at the risk of
significantly increasing propagation delay. (Figure 25) This
propagation delay is temperature sensitive.
To avoid acceptable time response, a minimum 100 mV
difference between Vin and VDET+ must be selected.
So, VDET+_max can be easily figured out just using a single
variable VDET−_typ.
For example, for NCP300LSN18T1G VDET−_typ = 1.8 V;
then
V DET+_max + 1.8
1.09 + 1.962 V
(eq. 8)
The NCP30X detection voltage option must be chosen such
that:
V CC_min t V DET+_max t V in_min
(eq. 9)
The significance of VCC_min < VDET+_max is that it makes
sure the the reset from NCP30X remains asserted (in RESET
hold state) till after the power supply exceeds the VCC_min
requirement; this prevents incorrect device (uP) initiation.
Having VDET+_max < Vin_min makes sure that the
NCP30X is able to start up when Vin is at the Vin_min.
The theoretical ideal VDET−_typ voltage option to be
selected by the user, VDET−_typ_ideal, can be given by the
following formula:
V DET−_typ_ideal +
(2

The following example shows how to select the device
voltage option in a real world application.
1. Power supply output specification: 3.3 V $3%
2. Microprocessor core voltage specification: 3.3 V
$5%
So, we have:
V in_min + 3.3 V * 3% + 3.201 V
(eq. 11)
V CC_min + 3.3 V * 5% + 3.135 V

Then the ideal voltage option = (3.201 + 3.135) / (2 * 1.09)
= 2.9064 V
Therefore, a device voltage option of 2.9 V will be the right
choice.

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.

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 NCP300/NCP301 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 through 4.
†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
*NCV prefix for automotive and other applications requiring site and control changes.
NCVxxx: Tlow = −40°C, Thigh = +125°C. Guaranteed by design.
