| 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. ! FEATURES " High Precision Detection Voltage 1.0% " Low Quiescent Current 0.9A typ.
