Pin Symbol Function
1OUT Output; output to the load; pin 1 and 5 must be externally shorted.
1)
1) Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability, the clamping
capability and decrease the current sense accuracy.
2IN Input; activates the power switch if shorted to ground.
3V

Supply Voltage; positive power supply voltage; tab and pin 3 are internally shorted.
4IS 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 Table 1 “Truth Table” on Page 21).
5OUT Output; output to the load; pin 1 and 5 must be externally shorted.
