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.

(*note 1)
(*note 1): The minimum Operating Voltage(V
OPL
) indicates the same value of the output voltage(V
OUT
) on
condition that V
OUT
becomes 10% or less of the input voltage(V
DD
).
