7.1
The standard diagnosis signal is a current sense signal proportional to the load current. The accuracy of the ratio
( k
connected to the current sense pin. It is recommended to use sense resistors R

Figure 15
In case of over-load as well as over-temperature, the voltage V
according input pin is high. This means, even if the overload disappears after the first thermal shutdown or when
the device keeps switching on and off in over-load condition (thermal toggling), the diagnosis signal ( V
constantly available. Please refer to
first thermal shutdown, the diagnosis signal (
