Foreign noise (from noise simulator, for example) may cause
example. It is advisable to review it carefully to learn optimal
malfunctions.
conditions.
To improve noise resistance, lay out printed-circuit patterns so that
wirings of IC to additional capacitors and resistors can be made as
short as possible.
1. Voltage applied to VS

equivalent circuits.) To design power supply, adapt it to IC,
considering IS characteristics.
2. Rectification for use of commercial AC line as power source.
4. Avoid SCRT output pin voltage from falling negative
below GND level.
5. Reset time applicable to reset timer circuit

IO=7.5µA. When SCR is on, power supply path is disconnected
from leak detector circuit. As shown in illustration below,
disconnection may inhibit V L from falling to 0.7V. Accordingly, reset
time may get shortened. To avoid shortage, predetermine a reset
time that includes extra time.

a) For VZ, select zener diode of 12V or less. (Prevent supply
voltage VS from exceeding absolute maximum rating of 15V.)
b).Escalated temperature may decrease supply voltage to
produce large current IS. In this case, RS limits IS.
3. For use of common DC power supply, set supply voltage VS
within range of 7 to 12V.
2. Resistor (R=180kΩ) at IREF pin
This resistor provides constant-reference-current source for IC.
(Constant current source protects IC against fluctuations in supply
voltage and ambient temperature.)
Since every circuit is characterized by resistance of this resistor,
the use of high-precision resistor (accuracy of ±2%) is
recommended.
Note. Predetermined reset time may get shortened by t.
