Function
Open-drain diagnostics output
Input for determining source/sink on outputs Q1 and Q2; when
Enable = Low, this pin serves as clock input for reading out
diagnostics
Input for activating or turning off device (all output transistors
turned off); Enable High = output active, Enable
Low = diagnostics
Supply voltage of IC
Power output with integrated free-wheeling diodes
Actual-current output: shared, open-source output of sink
transistors
Ground
Power output with integrated free-wheeling diodes
Determines turning back on of sink transistor by internally
driven, external RC element or external TTL trigger signal
Input for reference potential (nominal current) for nominal/
actual comparator
Input for actual current for nominal/actual comparator
