NJU7712/13
2ch VOLTAGE DETECTOR
!
GENERAL DESCRIPTION
The NJU7712/13 is a 2ch low quiescent current voltage
detector featuring high precision detection voltage.
The detection voltage is fixed internally with an accuracy
of 1.0%.
NJU7712 is Nch. Open Drain and NJU7713 of output
circuit form is a C-MOS output.
