NCP302LSN45T1 Datasheet PDF - ON Semiconductor

●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.
