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.

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.
