  • Description

    The NJU7705 is a low quiescent current voltage etector featuring high precision detection voltage.The detection voltage is internally fixed with an accuracy of 1.0%. The NJU7705 is 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 an external capacitor. Manual reset function can output reset signal irrespective of detection voltage. NJU7705 is a C-MOS output type. Small packaging makes NJU7705 suitable for space conscious applications.
