Output to the load. The pins
1,2,6 and 7 must be shorted with each other
especially in high current applications!

Positive power supply voltage, the tab is electrically connected to this pin.
In high current applications the tab should be used for the V

5 IS S
Diagnostic feedback providing a sense current proportional to the load
current; zero current on failure (see Truth Table on page 6)
6 OUT O
Output to the load. The pins
1,2,6 and 7 must be shorted with each other
especially in high current applications!

7 OUT O
Output to the load. The pins
1,2,6 and 7 must be shorted with each other
especially in high current applications!
