The standard diagnosis signal is a current sense signal proportional to the load current. The accuracy of the ratio

Figure 15
In case of over-current as well as over-temperature, the voltage V
according input pin is high. This means, even when the device keeps switching on and off in over-load condition,
the failure signal is constantly available. Please refer to
