Function
Diagnostic feedback: open drain, invers to input level
Logic ground
Input, activates the power switch in case of logical high signal
Positive power supply voltage, the tab is shorted to this pin
Sense current output, proportional to the load current, zero in
the case of current limitation of load current
Output, protected high-side power output to the load.
Both output pins have to be connected in parallel for operation
according this spec (e.g. kILIS).
Design the wiring for the max. short circuit current
Maximum Ratings at Tj = 25 °C unless otherwise specified

1) Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins (a 150
resistor in the GND connection is recommended).
2) RI = internal resistance of the load dump test pulse generator
3) VLoad dump is setup without the DUT connected to the generator according to ISO 7637-1 and DIN 40839
