The NCP/NCV302 and NCP/NCV303 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 under voltage detector with hysteresis and an externally programmable time delay generator. This combination of features prevents erratic system reset operation.The NCP/NCV302 series consists of complementary output devices that are available with either an active high or active low reset. The NCP/NCV303 series has an open drain N-channel output with an active low reset output.
