Abstract
A power controller includes bond wires that also act as fuses to protect the power controller from damage caused by a short circuit fault. The bond wires connect switching elements within the power controller with at least one output pin having at least one output rating. The bond wires themselves are configured so that the steady state current capability of each bond wire matches the output rating of its corresponding output pin. The power controller measures an output current to a load and adapts its protection functions depending on its programmed output rating. The output rating of the power controller may be controlled by the output rating of a particular pin or the number of switching elements that are turned on within the power controller.
