LOW VOLTAGE DETECTOR R3113D SERIES OUTLINE NO. EA-115-0506 The R3113D 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. Two output types, Nch open drain type and CMOS type are available. Since the package is ultra-small SON1408-3 (MFPAK), high density mounting on board is possible .

At Point "A", Vref > VDDx(Rb+Rc)/(Ra+Rb+Rc) is true, as a result, the output of comparator is reverse, = and output voltage becomes to GND level. The voltage level of Point A means detector threshold voltage, or (-VDET). Step 3. When the supply voltage is less than minimum operating voltage, the operation of output transistor becomes indefinite, and in the case that output is pulled up to VDD, the output voltage equals to VDD voltage. Step 4. The output voltage equals to GND level. Step 5. At Point "B", Vref > VDDxRb/(Ra+Rb) is true, Output of the comparator is reverse, and output voltage is = equal to the supply voltage, or (VDD). The voltage level of Point B means released voltage, or (+VDET). The difference between released voltage and detector threshold voltage is the detector threshold hysteresis. 10 R3113D TEST CIRCUITS Pull-up circuit is not necessary for CMOS Output type, or R3113DxxxC.

In Figure 9, When R3113Dxx1C is used, and if an impedance is connected between Voltage Supplier and the VDD Pin of R3113Dxx1C Series, the operation might be unstable by cross conduction current at detection. When R3113Dxx1A is used in Figure 9, if the value of R is set excessively large, voltage drop may occur caused by supply current of IC itself and Detector threshold may vary. 2. Wiring as shown in Figure 10 may cause the oscillation in both output types of R3113 Series. 18 |
