EARTH LEAKAGE CURRENT DETECTOR M5 4128L/FP MITSUBISHI <CONTROL / DRIVER IC> PRE CAUT IO N S FO R A PPLIC A TIO N Note that the improvement examples in the following precautions for application of M54128FP/L are merely examples. 1.VS applied voltage (1) ls circuit current (clamp circuit characteristics of the equivalent circuit) is as shown in TYPlCAL CHARAC- TERISTICS figure 1 on page 9. Attention should be given to the circuit current when designing the power supply circuit. (2) Use of the lC by rectifying commercial power supply a)As Vz, be sure to use zener diode of 12V or less (not exceeding the absolute maximum rating of 15V). b)At high temperatures, clamp voltage decreases and ls increases. lncrease of ls will be restricted at Rs, however. (3)lf normal DC power supply is used, use the lC at Vs=7to10V. 2.R esistorofIR EF pin (R = 130k W Reference constant curr ent source of the lC (for restraining fluctuations in supply voltage characteristics and ambient temperature characteristics). Since this resistor determines the characteristics of each circuit, use of high-precision resistor ( 2%) is recommended. 3.Layoutofprinted circuitboard External noise (noise simulator etc.) may cause faulty operation of the lC. To improve the noise immunity, layout the printed circuit board so that the wiring of the external C and R is made as short as possible. Special attention should be given to the wiring of the condensers connected to Vs, Vcc and S CRT pins. 4.B e careful that the voltage of SC R T output pin does not becom e lower than the G N D level. 5.C hange insensitivity due to insulation deterioration If the insulation of ZCT input pin from the high voltage part might deteriorate, improvement might be expected by connecting a resistor of about R=100k W between V REF pin and GND. It should be noted that the circuit current will increase at I 2.7V/R (approx.). 6.C lam p diode ofIBLIinputpin As shown in the equivalent circuit, it is made up of series resistor (approx. 2k W ) and seven stages of forward diode. (1) At high temperatures, the drop in diode V F may decrease the clamp voltage of the pin. If the voltage approaches the reference level of the comparator (2.4V) and current leaks occur, the overvoltage detection level may slightly fluctuate. Form the detection circuit as the figure below. It is recommended that R , R and V Z be set as shown below. (2) During excessive input, as shown above, setting should be made so that the input pin voltage becomes 4.3V or lower (to prevent the saturated comparator circuit from operating).

EARTH LEAKAGE CURRENT DETECTOR M5 4128L/FP MITSUBISHI <CONTROL / DRIVER IC> 7.R esettime in resetcircuit This circuit is designed as a timer circuit of V L = 0.7V, V H = 2.5V and lo = 10 m A. When SCR is ON, the power supply route of the leakage detection and abnormal voltage detection circuits are shut off, VL does not drop to 0.7V as shown below and therefore reset time may become shorter. Set the reset time somewhat longer in advance. 8.A pplication of leakage detection function to time delay function As shown in the figure below, by applying the neutral conductor open-phase protection function, it is possible to provide the leakage detection function with time delay function (several 100ms). ln this case, however, the neutraI conductor open- phase protection function disappears. Pin No. in parentheses are of L type. T = = 55ms 0.33 m F x (2.4 - 0.7) m A C x (V H - V L I Note. t : time shorter than setting value
