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. k
ILIS
).
