NJU7709

NJU7708/09 VOLTAGE DETECTOR with Delay Function GENERAL DESCRIPTION The NJU7708/09 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%. The NJU7708/09 are useful for preventing malfunction of microcomputer or DSP etc. through detect a drop in voltage of battery or power supply. 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.
