Abstract
An electrical device includes a power supply circuit configured to provide a first voltage and a second voltage, and a first verification circuit configured to derive a first and a second internal voltage from the first voltage, to compare the first and second internal voltages, and to generate a first output signal based on the comparison. The electrical device includes a second verification circuit including a first input terminal for the first voltage and a second input terminal for the second voltage, and configured to compare the first and second voltages and to generate a second output signal based on the comparison. Furthermore, the electrical device includes a combination circuit configured to generate a third output signal if the first output signal or the second output signal is indicative of the first voltage or the second voltage being outside a tolerance range.
