Pin Definitions and Functions

Pin No.

Symbol

Function

DIAG

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

4, 12

Supply voltage of IC

5, 6

Power output with integrated free-wheeling diodes

7, 9

Sense

Actual-current output: shared, open-source output of sink

transistors

GND

Ground

10, 11

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

NOM

Input for reference potential (nominal current) for nominal/

actual comparator

ACT

Input for actual current for nominal/actual comparator
