Pin Symbol Function

1 OUT O Output; output to the load; pin 1 and 5 must be externally shorted* .

2 IN I Input; activates the power switch if shorted to ground.

Tab/(3) Vbb + Supply Voltage; positive power supply voltage; tab and pin3 are internally

shorted.

4 IS S Sense Output; Diagnostic feedback; provides at normal operation a sense

current proportional to the load current; in case of overload, overtemperature and/or short circuit a defined current is provided (see Truth Table on page 8)

5 OUT O Output; output to the load; pin 1 and 5 must be externally shorted* .

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