Abstract
A class D audio amplifier with an output stage is provided. The class D audio amplifier includes a plurality of power transistors coupled in cascade between a first DC supply voltage and a second DC supply voltage. The class D audio amplifier also includes a plurality of gate drivers having respective inputs coupled to a modulated audio signal and configured to generate respective modulated gate drive signals to the plurality of power transistors. A first overload protection circuit includes a model transistor possessing electric characteristics representative of a first power transistor of the output stage for determining a drain-source reference voltage of the model-transistor and this drain-source reference voltage may be utilized to indicate an overload event or condition of the first power transistor.
