NJRC NJU7705 Voltage detector Datasheet

NJU7704/05
VOLTAGE DETECTOR
! GENERAL DESCRIPTION
The NJU7704/05 is a low quiescent current voltage detector
featuring high precision detection voltage.
The detection voltage is internally fixed with an accuracy of
1.0%. A time delayed reset can be accomplished with an
external capacitor.
NJU7704 is Nch. Open Drain and NJU7705 is a C-MOS
output type.
