EARTH LEAKAGE CURRENT DETECTOR MITSUBISHI <CONTROL / DRIVER IC> PRE CAUT IO N FO R APP LICAT IO N Described below are precautions on usage of the M54133FP and the M54133GP. Note that each precaution presents a still better example. It is advisable to review it carefully to learn optimal conditions. 1.VoltageappliedtoV S 1. Fig.1 shows characteristics of circuit current I S S characterizes clamp circuit shown in INPUT/OUTPUT equivalent circuits.) To design power supply, adapt it to IC, considering I S characteristics. 2. Rectification for use of commercial AC line as power source. Fig.1 C HARACT ERISTICS O F V S TO I S a) For V Z , select zener diode of 12V or less. (Prevent supply voltage V S from exceeding absolute maximum rating of 15V.) Escalated temperature may decrease supply voltage to produce large current I S . In this case, R S limits I S 3. For use of common DC power supply, set supply voltage V S within range of 7 to 12V. 2.Resistor(R=180k W )atI RE F 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%) i s recommended. 3.Laying out printed-circuitboard 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 V S of pin , V CC of pin , and SCRT of pin . 4. Avoid SCRT output pin voltage from falling negative below GND level. 5.Reset timeapplicabletoresettimercircuit The M54133 has reset timer circuit of V L =0.7V, V H =2.4V, and I O =7.5 m A. When SCR is on, power supply path is disconnected from leak detector circuit. A s 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.
