General Description

The NJU7707 is a high precision voltage detector with a built-in delay time generator of fixed time.The NJU7706/07 is useful for preventing malfunction of microprocessor or DSP through monitoring power supply voltage.The delay function achieves set wait time when supply voltage is unstable. Moreover, the delay function can make a sequence that other devices in application work and stabilize before microcomputer or DSP works.The detection voltage is internally fixed with an accuracy of 1.0%,and three fixed delay times 50ms, 100ms and 200ms are available. Manual reset function can output reset signal irrespective of detection voltage.NJU7706 is Nch. Open Drain and NJU7707 is a C-MOS outputtype.Small packaging makes NJU7706 and NJU7707 suitable for space conscious applications.
