R3117x SERIES LOW VOLTAGE DETECTOR with SENSE pin NO.EA-186-080617 OUTLINE The R3117x series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example. Each of these ICs consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy internally and does not require any adjustment. The tolerance of the detector threshold is 15mV (-VDET < = 1.5V) or 1.0% (1.5V< -VDET). Since the sense pin is separated from the VDD pin of the IC, therefore, even if the sense pin voltage becomes to 0V, the output voltage keeps its "L" level. Two output types, Nch open drain type and CMOS type are available. Three types of packages, SOT-23-5, SC-88A, and DFN(PLP)1010-4 are available.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 5 R3117x ELECTRICAL CHARACTERISTICS BY DETECTOR THRESHOLD * R3117x07xA/C to R3117x50xA/C Bold values are checked and guaranteed by design engineering at -40C < = Topt < = 105C, unless otherwise noted.

At Point "A", Vref > = VSENSEx(Rb+Rc)/(Ra+Rb+Rc) is true, as a result, the output of comparator is reversed from "H" to "L", therefore the output voltage becomes the GND level. The voltage level of Point A means a detector threshold voltage (-VDET). (When the supply voltage is lower than the minimum operating voltage, the operation of the output transistor becomes indefinite. The output voltage is equal to the GND level.) Step 3. At Point "B", Vref < = VSENSExRb/(Ra+Rb) is true, as a result, the output of comparator is reversed from "L" to "H", then the output voltage is equal to the pull-up voltage.

At Point "A", Vref > = VSENSEx(Rb+Rc)/(Ra+Rb+Rc) is true, as a result, the output of comparator is reversed from "H" to "L", therefore the output voltage becomes the GND level. The voltage level of Point A means a detector threshold voltage (-VDET). (When the supply voltage is lower than the minimum operating voltage, the operation of the output transistor becomes indefinite. The output voltage is equal to the GND level. Step 3. At Point "B", Vref < = VSENSExRb/(Ra+Rb) is true, as a result, the output of comparator is reversed from "L" to "H", then the output voltage is equal to the supply voltage (VDD). The voltage level of Point B means a released voltage (+VDET). ) The difference between a released voltage and a detector threshold voltage is a detector threshold hysteresis. 10 R3117x Power supply injection order The R3117xxxxA/C Series supervise the voltage of the SENSE pin. VDD pin and SENSE pin can be used at the same voltage level. Likewise, VDD pin and SENSE pin can be used at the different voltage level. If the VDD pin and SENSE pin are used at different voltage level, regarding the start-up sequence, force the voltage level to VDD pin prior to the SENSE pin. If the SENSE pin voltage is equal or more than the released voltage (+VDET), DOUT pin becomes "H". Besides, a voltage beyond VDD pin is also acceptable to SENSE pin. Concerning the R3117xxxxA series (Nch open drain output type), DOUT pin must be pulled-up with an external resistor. VDD +VDET VSENSE VOUT t Fig.1 Turn on sequence Outside setting of the detection voltage To monitor the voltage more than 5.0V or if the different detector threshold with using lower threshold device, divider resistors can be applied to the SENSE pin. In this usage, some error range will be generated to the detector threshold voltage caused by the internal resistor RSENSE (Fig.3) of the IC. Supposed that the detector threshold voltage is described as Vs, the next equation will be true. VS = -VDET x (Ra+Rb)/Rb. However, actually an error includes by SENSE resistance (RSENSE) of the IC inside. (Figure 3) Ia = Ib + ISENSE .......................................(1) Ib = -VDET / Rb .......................................(2) Thus, Ia = -VDET / Rb + ISENSE .......................................(3) Therefore, VS = -VDET + Ia x Ra .......................................(4) 11 R3117x Put Equation (3) into Equation (4), then VS = -VDET x (Ra + Rb) / Rb + Ra x ISENSE Ra x ISENSE is an error in VS. Ra x ISENSE = Ra x (-VDET) / RSENSE = -VDET x Ra / RSENSE The error range is -VDET x Ra/RSENSE (Fig.3) and to make it small, choosing the low detector threshold voltage type and set the resistance values Ra, Rb as RSENSE >>Ra. Refer to the electrical characteristics table to see the RSENSE value.

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.
