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.

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

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.
