R3117 Series
Voltage Detector with SENSE pin

Product Specifications

The R3117 Series are CMOS-based voltage detector ICs. Since R3117 has a SENSE pin for monitoring voltage separately from the power pin, its reset signal does not become unstable as long as power supply is secured and the "L" can be maintained. The R3117 is offered in a 5-pin SOT-23-5 package. It is also offered in 5-pin SC-88A and 4-pin DFN(PLP)1010-4 packages, 1 mm x 1 mm, for consumer applications.

PRODUCT LONGEVITY PROGRAM

R3117Q and R3117N operate PRODUCT LONGEVITY PROGRAM.
This program has been introduced to help customers select the most appropriate part for applications that require long life cycles.


Operating Temperature Range : -40°C to 105°C


Notice: R3117xxx1A/C, R3117Qxx2A/C

If the SENSE pin voltage of R3117xxx1A/C and R3117Qxx2A/C make the gradual curve by raising 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.


Notice: R3117xxx3A/C, R3117Qxx4A/C

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 datasheet.
