R3112x SERIES
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-087-070112
OUTLINE
The R3112x 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, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high accuracy internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. Three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6 can be selected so that high density mounting on boards is possible.

ABSOLUTE MAXIMUM RATINGS Absolute Maximum ratings are threshold limit values that must not be exceeded ever for an instant under any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only and do not necessarily imply functional operation below these limits.

Fig. 2 Operation Diagram 1. Output voltage is equal to supply voltage. (As for Nch open drain type, equal to pull-up voltage.) 2. When the supply voltage is down to the detector threshold voltage level(Point A), Vref > VDDx(Rb+Rc)/(Ra+Rb+Rc) is true, then output of the comparator is reversed from "L" to "H", therefore = output voltage becomes GND level. 3. When the supply voltage is lower than minimum operating voltage, the operation of output transistor is indefinite. In the case of Nch open drain type, output voltage is equal to pull-up voltage. 4. Output Voltage becomes GND level. 5. When the supply voltage is higher than released voltage (Point B), Vref < VDDxRb/(Ra+Rb) is true, then = output of the comparator reaches the threshold level, and Output of Shmitt Trigger is reversed from "H" to "L", then output voltage is equal to supply voltage. (As for Nch open drain type, equal to pull-up voltage.) ) The difference between released voltage and detector threshold voltage means hysteresis range voltage.

Capacitor Voltage
CD Pin Threshold Voltage (VTCD) GND
Output Voltage GND Output Delay Time(tD)
When the supply voltage which is higher than released voltage is forced to VDD pin, charge to an external capacitor starts, then capacitor voltage increases. Until the capacitor voltage reaches to CD Pin threshold voltage, output voltage maintains "L". When the capacitor voltage becomes higher than CD pin threshold voltage, output voltage is reversed from "L" to "H". Where, the time interval between the rising edge of supply voltage and output voltage reverse point means output delay time.
*
Output Delay Time
Output Delay Time (tD) can be calculated with the next formula. tD=0.69xRDxCD(s)
RD is internal resistor and set at 6.5M(Typ.) typically. CD(F) describes the capacitance value of an external capacitor. Therefore, tD=0.69x6.5x106xCD(s)

Figure A
Figure B
Figure C
When R3112xxx1A (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 R3112xxx1C (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 R3112xxx1C with the connection in Figure A or Figure B. The connection in Figure C may cause the oscillation in both R3112xxx1C (CMOS Output) and R3112xxx1A (Nch Open Drain Output), therefore do not use R3112xxx1x Series with the connection in Figure C.
