TECHNICAL NOTES
R5105N, R5106N, R5107G, R5109G
When R510xxxx1A (Nch Open Drain Output Type) is used in Figure A or Figure B, if impedance of Voltage
Supply pin, VDD and VDD 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 R510xxxx1C (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 R510xxxx1A (Nch Open Drain Output) and
R510xxxx1C (CMOS Output), therefore do not use R510xx Series with the connection in Figure C.
