RICOH R3113D

LOW VOLTAGE DETECTOR
R3113D SERIES
NO. EA-115-0506
OUTLINE
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 .

DEFINITION OF OUTPUT DELAY TIME
Output Delay Time tPLH is defined as follows:
1. In the case of Nch Open Drain Output:
Under the condition of the output pin (OUT) is pulled up through a resistor of 470kΩ to 5V, the time interval
between the rising edge of VDD pulse from 0.85V to (+VDET)+ 1.0V and becoming of the output voltage to 2.5V.
2. In the case of CMOS Output:
The time interval between the rising edge of VDD pulse from 0.85V to (+VDET)+ 1.0V and becoming of the
output voltage to (VDD/2) V.

Step 1. The output voltage is equal to the supply voltage (VDD).
Step 2. At Point “A”, Vref >
= VDD×(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 >
= VDD×Rb/(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.

1. 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.
