Note that each precaution presents a still better example. It is advisable to review it carefully to learn optimal conditions. 1. Voltage applied to VS (1) Fig.1 shows characteristics of circuit current IS. (IS characterizes clamp circuit shown in INPUT/OUTPUT equivalent circuits.) To design power supply, adapt it to IC, considering IS characteristics. (2) Rectification for use of commercial AC line as power source. RS VS COMMERCIAL AC LINE IC VZ 3 IS (mA) +25°C 2 +85°C -20°C 1 0 ∫∫ 12 13 14 15 VS(V) Fig. 1 CHARACTERISTICS OF VS TO IS 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. 3. Laying out printed-circuit board Foreign noise (from noise simulator, for example) may cause malfunctions. 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. Carefully design patterns especially for wiring capacitors to VS of [16] pin , VCC of [3] pin , and SCRT of [8] pin. 4. Avoid SCRT output pin voltage from falling negative below GND level. Rev.1.0, Sep.16.2003, page 8 of 17 M54133FP/GP 5. Reset time applicable to reset timer circuit The M54133 has reset timer circuit of VL=0.7V, VH=2.4V, and IO=7.5µA. When SCR is on, power supply path is disconnected from leak detector circuit. As shown in illustration below, disconnection may inhibit VL from falling to 0.7V. Accordingly, reset time may get shortened. To avoid shortage, predetermine a reset time that includes extra time. T= CX(VH-VL) = 0.33µFX(2.4-0.7) =75ms IO 7.5µA 3.8V WAVEFORMS AT OFFC PIN 2.4V 0.7V 75ms WAVEFORMS AT SCRT PIN 0V t=10ms Note. Predetermined reset time may get shortened by t.
