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.

Each series features a highly accurate undervoltage 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.
