NJU7700/01
VOLTAGE DETECTOR
GENERAL DESCRIPTION
The NJU7700/01 is a high precision and low quiescent current
voltage detector.
The detection voltage is internally fixed with an accuracy of 1.0%.
The NJU7700/01 are useful for preventing malfunction of
microcomputer or DSP etc. through detect a drop in voltage of battery
or power supply.
NJU7700 is Nch. Open Drain and NJU7701 is a C-MOS output
type.
Small packaging makes NJU7700 and NJU7701 suitable for space
conscious applications.
