Pin

Symbol

Function

1

OUT

O

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

other especially in high current applications!*)

2

IN

I

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

Tab/(3)

Vbb

+

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

4

IS

S

Diagnostic feedback providing a sense current proportional to the load

current; high current on failure (see Truth Table on page 6)

5

OUT

O

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

other especially in high current applications!*)

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

and decrease the current sense accuracy
