LOW VOLTAGE DETECTOR
R×5VT SERIES
OUTLINE
The R×5VT Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply current
by CMOS process, which can be operated at an extremely low voltage and is used, for instance, for system reset.
Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an output
driver and a hysteresis circuit. The detector threshold is fixed with high accuracy.
The R×5VT Series are operable by a lower voltage than that for the R×5VL Series, and can be driven by a sin-
gle battery.
Two output types, Nch open drain type and CMOS type, are available. Three types of packages, TO-92, SOT-
89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available.

Output Delay Time tPLH is defined as follows:
1. In the case of Nch Open Drain Output:
When the time at which a pulse voltage which increases from 0.7V to +VDET+2.0V is applied to VDD is Time A, and
the time at which the output voltage reaches 2.5V under the conditions that the output pin (OUT) is pulled up
to 5V by a resistor of 470kΩ is Time B, the time period from Time A through Time B.
2. In the case of CMOS Output:
When the time at which a pulse voltage which increases from 0.7V to +VDET+2.0V is applied to VDD is Time A, and
the time at which the output voltage reaches the voltage of (+VDET+2.0V)/2 is Time B, the time period from
Time A through Time B.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum ratings are threshold limit values that must not be exceeded even 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.

Step 1. Output Voltage is equal to Power Source Voltage (VDD).
Step 2. When Input Voltage to Comparator reaches the state of Vref≥VDD·(Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage –VDET), the output of Com-
parator is reserved, so that Output Voltage becomes GND.
Step 3. In the case of CMOS Output, Output Voltage becomes unstable when Supply Voltage (VDD) is smaller than Minimum Operating Voltage. In the
case of Nch Open Drain Output, a pulled-up voltage is output.
Step 4. Output Voltage becomes equal to GND.
Step 5. When Input Voltage to Comparator reaches the state of Vref≤VDD· (Rb)/(Ra+ Rb) at Point B (Released Voltage +VDET), the output of Comparator is reversed,
so that Output Voltage becomes equal to Supply Voltage (VDD).

FIG.9
1. When R×5VT××C (CMOS Output) is used in FIG. 9, this IC may oscillate by the through-type current at the
detection when impedance is connected between Power Source VDD and R×5VT VDD Pin.When
R×5VT××A (Nch Open Drain Output) is used in FIG. 9, and R becomes excessively large, Detector Threshold
may be varied because of the voltage drop of the supply current in the IC itself.
2. The connection as shown in FIG. 10 may cause the oscillation in both R×5VT××C (CMOS Output) and
R×5VT××A (Nch Open Drain Output).

TZ type tape is not in the form of a reel, but is
packed in a zigzag state in a box.Therefore, the
tape can be used as either an RF type tape or an
RR type tape,depending upon the pulling out
