8.1
In order to use the digital feedback function of the device, there is serial resistor necessary between the IN pin and
the driver (micro controller)
To calculate the value of this serial resistor on the input pin three device conditions as well as the driver (micro
controller) abilities needs to be taken into account.
The driver must be capable of driving at least

Note: This is a very simplified example of an application circuit. The function must be verified in the real application.

During normal operation V
During fault condition the max. capability of the driver (micro controller) must not be exceeded and the logic
low level at DI must be ensured by a voltage drop over the serial resistor R
flowing.
During fault state the device keeps protection active as long as it can sink more than the threshold current
I
signal. So to avoid an unintentional switch ON/OFF behavior, the input current must be above this threshold.
