Abstract
In accordance with the teachings of the present invention, a semiconductor device having voltage output function trim circuitry and a method for the same are provided. In a particular embodiment, the method includes electrically coupling to a main circuit of a semiconductor device a plurality of resistances each operable to determine a different output voltage range of the main circuit, electrically coupling each of the plurality of resistances to a respective one of a plurality of fuses, electrically coupling each of a plurality of fuses to a respective one of a plurality of function trim pads, and electrically decoupling all but one of the plurality of resistances by applying a respective current between the respective function trim pads and an output node sufficient to open the respective fuses.
