General Description
The NJU7709 is a low quiescent current voltage detector with delay function featuring high precision detection voltage.The detection voltage is internally fixed with an accuracy of 1.0% accuracy. The NJU7708/09 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.Delay time can be set by logical combination from 4-delay time.NJU7708 is Nch. Open Drain and NJU7709 is a C-MOS output type.Small packaging makes NJU7708 and NJU7709 suitable for space conscious applications.
