A method includes receiving a set of voltages comprising at least a first voltage, a second voltage, and a third voltage and biasing a well of a transistor based on the extreme voltage of the set of voltages. Biasing the well of the transistor can include concurrently providing a first signal and a second signal based on a comparison of the first voltage and the second voltage and selectively coupling the well of the transistor to a source of the extreme voltage of the set of voltages based on the first signal, the second signal, and the third voltage. An electronic device comprises a transistor and a power switching module. The power switching module includes a set of inputs, each input configured to receive a corresponding one of a set of voltages comprising at least a first voltage, a second voltage, and a third voltage, and includes an output coupled to a well of the transistor, the output configured to provide the extreme voltage of the set of voltages.
