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 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.
