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.

Abstract: A system may include a digital sensor system including a sensor element and a digital interface. The digital interface may provide a wake-up signal based on a sensing action being performed by the sensor element after a predefined event is detected by the digital sensor system. The system may include a microcontroller to receive the wake-up signal provided by the digital interface, and wake from a sleep mode based on receiving the wake-up signal provided by the digital interface.
