Figure A
Figure B
As shown wiring in Figure A and Figure B may cause unstable operation by cross conduction current at
detection of all types of R313xN Series. The detector threshold may shift because of voltage drop by
consumption current of this IC itself.
At the power-on state, if VDD starts up from minimum input voltage (1V) or less very rapidly, the internal
initialization may not be finished, and output may be unstable. If the transient time from the minimum input
voltage to the detector threshold level at the power-on state is 30
s or less, fully evaluation is necessary.
