| NJU7706/07 VOLTAGE DETECTOR s GENERAL DESCRIPTION The NJU7706/07 is a high precision voltage detector with a built-in delay time generator of fixed time. The detection voltage is fixed internally with an accuracy of 1.0%, and three delay times 50ms, 100ms and 200ms are available. NJU7706 is Nch. Open Drain and NJU7707 of output form is a C-MOS output. s PACKAGE OUTLINE NJU7706/07F s FEATURES qHigh Precision Detection Voltage qLow Quiescent Current qDetection Voltage Range qDelay Time(Built-in Fixed Type) qON/OFF switch of delay time (DS pin) qManual Reset qOutput Circuit Form qPackage Outline 1.0% 1.8A typ. 1.5 6.0V(0.1V step) 50ms /100ms /200ms(Built-in Fixed Type) 2type: Active "H" / Active "L" NJU7706: Nch.
