NCP302, NCP303
Voltage Detector Series
with Programmable Delay
The NCP302 and NCP303 series are second generation ultra–low
current voltage detectors that contain a programmable time delay
generator. These devices are specifically designed for use as reset
controllers in portable microprocessor based systems where extended
battery life is paramount.
http://onsemi.com
Each series features a highly accurate under voltage detector with
hysteresis and an externally programmable time delay generator. This
combination of features prevents erratic system reset operation.
The NCP302 series consists of complementary output devices that
are available with either an active high or active low reset. The
NCP303 series has an open drain N–channel output with an active low
reset output.

TSOP–5
SN SUFFIX
CASE 483
The NCP302 and NCP303 device series are available in the
TSOP–5 package with seven standard under voltage thresholds.
Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps
can be manufactured.

NCP302 and NCP303 series are measured with 10 pF capacitive load. NCP303 has an additional 470 k pullup resistor connected from the reset output to +5.0 V.
Reset output voltage waveforms are shown for the active low `L' devices. For active high `H' devices, the reset output voltage waveforms are inverted. Output
time delay t and t are dependent upon the delay capacitance. Refer to Figures 11, 12, and 13. The upper detector threshold, V is the sum of the lower

The NCP302 and NCP303 series devices consist of a
precision voltage detector that drives a time delay generator.
Figures 36 and 37 show a timing diagram and a typical
N–channel MOSFET and allow pullup resistor R to charge
external capacitor C , thus creating a programmable delay
for releasing the reset signal. When the voltage at Pin 5
exceeds the inverter/buffer threshold, typically 0.675*V ,

nominal level and it is greater than the voltage detector upper
the reset output will revert back to its original state. The reset
output time delay versus capacitance is shown in Figures 11
through 13. The voltage detector and inverter/buffer have
built–in hysteresis to prevent erratic reset operation.
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 and time
delay are required. Figures 37 through 39 show various
application examples.

MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS
Surface mount board layout is a critical portion of the
total design. The footprint for the semiconductor packages
must be the correct size to insure proper solder connection
interface between the board and the package. With the
correct pad geometry, the packages will self align when
subjected to a solder reflow process.
