Pin

Symbol

Function

1

OUT

Output to the load. The pins 1 and 5 must be shorted with each other

2

IN

Input, activates the power switch in case of short to ground

3

Vbb

Positive power supply voltage, the tab is electrically connected to this pin.

4

IS

Diagnostic feedback providing a sense current proportional to the load

current; zero current on failure (see Truth Table on page 7)

5

OUT

Output to the load. The pins 1 and 5 must be shorted with each other

3)

Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability

and decrease the current sense accuracy

4)

Otherwise add up to 0.5 m
