Product Summary
The ncp303lsn45t1g is a second generation ultra-low current voltage detector that contain a programmable time delay generator. The ncp303lsn45t1g is specifically designed for use as reset controllers in portable microprocessor based systems where extended battery life is paramount. The ncp303lsn45t1g features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator. This combination of features prevents erratic system reset operation. Applications are (1)Microprocessor Reset Controller; (2)Low Battery Detection; (3)Power Fail Indicator; (4)Battery Backup Detection.
