NCP302HSN45T1G

监控电路 4.5V Detector w/Reset Hgh

Voltage Detector Series  with Programmable Delay

The NCP302HSN45T1G 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.
