NJU7702/03
VOLTAGE DETECTOR
!
GENERAL DESCRIPTION
The NJU7702/03 is a high precision and low quiescent current
voltage detector.
The detection voltage is internally fixed with an accuracy of
1.0%.
The NJU7702/03 are useful for preventing malfunction of
microcomputer or DSP etc. through detect a drop in voltage of battery
or power supply.
NJU7702 is Nch. Open Drain and NJU7703 is a C-MOS output
type.
Small packaging makes NJU7702 and NJU7703 suitable for
space conscious applications.
