... C which limits the power dissipation to safe levels. LTC1478 Operation The LTC1478 dual protected switch can be thought of as two independent LTC1477 single protected switches. The input supply voltages may be from separate power sources. The ground connection, however, is common to both channels and must be connected to the same potential ...

A couple of examples are helpful nominal load of 1A was controlled by the switch configured to current limit at 2A (all V together), the R would be 0.07 and the voltage DS(ON) drop across the switch would be 70mV. The power dissipated by the switch would only be 70mW ...
