TECHNICAL NOTES
When R3117xxxxA/C is used in the circuit as SENSE pin and VDD pin are connected each other such as in
Figure A, if the value of R1 is set excessively large, the dropdown voltage caused by the consumption current of
IC itself, may vary the detector threshold and the released voltage. Also, if the value of R1 is set excessively
large, there may cause oscillation generated by cross conduction current with released operation.
When R3117xxxxA/C is used in the circuit as SENSE pin and VDD pin are connected each other such as in
Figure B, if the value of R1 is set excessively large, the dropdown voltage caused by the consumption current of
IC itself, may vary the detecor threshold and the released voltage.
Also, if the value of R1 is set excessively large, there may be delay in start-up and may cause oscillation
generated by cross conduction current. Furthermore, if the value of R1 is set large and the value of R2 is set
small, released voltage level may shift and the minimum operating voltage may differ. If the value of R2 is set
excessively small from R1, release may not occur and may cause oscillation.
