NJU7707

NJU7706/07 VOLTAGE DETECTOR GENERAL DESCRIPTION The NJU7706/07 is a high precision voltage detector with a built-in delay time generator of fixed time. The NJU7706/07 is useful for preventing malfunction of microprocessor or DSP through monitoring power supply voltage. The delay function achieves set wait time when supply voltage is unstable. Moreover, the delay function can make a sequence that other devices in application work and stabilize before microcomputer or DSP works. The detection voltage is internally fixed with an accuracy of 1.0%, and three fixed delay times 50ms, 100ms and 200ms are available. Manual reset function can output reset signal irrespective of detection voltage. NJU7706 is Nch. Open Drain and NJU7707 is a C-MOS output type. Small packaging makes NJU7706 and NJU7707 suitable for space conscious applications. PACKAGE OUTLINE NJU7706/07F FEATURES High Precision Detection Voltage ±1.0% Low Quiescent Current 1.3µA typ.
