Pin Symbol
Function
1 OUT
Output; output to the load; pin 1 and 5 must be externally shorted.1)
2 IN
Input; activates the power switch if shorted to ground.
3 Vbb
4 IS
Supply Voltage; positive power supply voltage; tab and pin 3 are internally shorted.
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).
5 OUT
Output; output to the load; pin 1 and 5 must be externally shorted.1)
TAB Vbb
Supply Voltage; positive power supply voltage; tab and pin 3 are internally shorted.
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.

Power Stages
The energy, which is converted into heat, is limited by the thermal design of the component. For given starting
currents the maximum allowed inductance is therefore limited. See Figure 10 for the maximum allowed
inductance at Vbb=12V.
