LOW VOLTAGE DETECTOR

RN5VS SERIES

OUTLINE

The RN5VS 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 RN5VS 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. Since the package for these ICs are

SOT-23-5 (Mini-mold) package, high density mounting of the ICs on board is possible.

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 +V

DET+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 +V

DET+2.0V is applied to VDD is Time A, and

the time at which the output voltage reaches the voltage of (+V

DET+2.0V)/2 is Time B, the time period from

Time A through Time B.

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.

OPERATION

FIG. 1 Block Diagram

Operation Diagram

Step 1. Output Voltage is equal to Power Source Voltage (VDD).
Step 2. When Input Voltage to Comparator reaches the state of Vref≥V

DD·(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 (V

DD) 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≤V

DD · (Rb)/(Ra+ Rb) at Point B (Released Voltage +VDET), the output of Comparator is

reversed, so that Output Voltage becomes equal to Supply Voltage (V

DD).

RN5VS

××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.
