description In an aspect of the disclosure, a class D power amplifier with an overcurrent protection (OCP) circuit is provided. The class D power amplifier includes a plurality of output transistors, and the OCP circuit is mirrored to at least one output transistor of the plurality of output transistors in a closed-loop feedback configuration for precisely controlling a sensing current of the OCP circuit with respect to an output current of the at least one output transistor. The class D power amplifier with the OCP circuit in the closed-loop feedback configuration mitigates a variation in a current threshold value for triggering interruption of the class D power amplifier.
