TECHNICAL NOTES

When R3111xxxxA/B (Nch Open Drain Output Type) is used in Figure A or Figure B, if impedance of Voltage

and V
DD
of this IC is large, detector threshold level would shift by voltage dropdown caused by
the consumption current of the IC itself. Released voltage may also shift and delay time for start-up might be
generated by this usage.
When R3111xxxxC (CMOS Output Type) is used in Figure A or Figure B, Output level could be unstable by
cross conduction current which is generated at detector threshold level or at released voltage level, therefore, do
not use this IC with the connection in Figure A or Figure B.
The connection in Figure C may cause the oscillation in both R3111xxxxC (CMOS Output) and R3111xxxxA/B
(Nch Open Drain Output), therefore do not use R3111x Series with the connection in Figure C.
