- *1 Manual reset pin
- *2 in Detector Threshold Voltage(-VDET)=1.5V, in Released
- *3 Reset Signal "H": only SON1612 -6, SC-82AB, SC-88A
- *4 If the SENSE pin voltage of R3117xxx1A/C and R3117Qxx2A/C make the gradual curve by rasing 0.5V/ms or less, it may cause noise when the output voltage is switched from low to high. Please use R3117xxx3A/C and R3117Qxx4A/C Series for new designs instead of these products to avoid the above problem.
- *5 R3117xxx3A/C and R3117Qxx4A/C Series may cause the malfunction (miss detection), in the case of its VDD pin voltage changes very rapidly. Please check the details in the page 11 of the datasheet.
- *6 SENSE pin input voltage range : 0V to 36.0V
- *7 The R3150N has an internal setting for the Detector Threshold Voltage and Released Voltage, as well as a setting for the Detect Output Delay Time and Release Output Delay Time by external capacitor.
