Absolute Maximum Ratings are those values beyond which the life of a device may be destroyed. We cannot be defined the
failure mode, such as short mode or open mode. Therefore a physical security countermeasure, like fuse, is to be given
when a specific mode to be beyond absolute maximum ratings is considered.
Recommended value of RL Resistar is over 50kΩ (VDET=1.5~4.8V),over 100kΩ (VDET=0.9~1.4V).
unexpected operations. Application values in these conditions should be selected carefully. If 10MΩ leakage is assumed
between the CT terminal and the GND terminal, 1MΩ connection between the CT terminal and the V
recommended. Also, if the leakage is assumed between the V
should be less than 1/10 of the assumed leak resistance.

Please make sure all pins that are over ground even if include transient feature.
Be sure to check the electrical characteristics, that are one the tentative specification will be changed by temperature,
supply voltage, and external circuit.
Please put into the to reject noise between V
If extremely big capacitor is used, transient response might be late. Please confirm sufficiently for the point.

IC on circuit board please is unusually cautious about the orientation and the position of the IC. When the orientation is
mistaken the IC may be destroyed.
Mal-function may happen when the device is used in the strong electromagnetic field.
