Abstract
The operating voltage is monitored in a microcontroller having associated output stages which are used to control components. In the case of over-voltage, the output stage is disconnected. Two technology-related, voltage monitoring devices working in different operating voltage ranges are provided. Due to the combination thereof, a highly precise disconnection threshold and a greater area for the operating voltage, which is to be monitored, can be obtained. If a malfunction of an over-voltage occurs, the output stages can be disconnected in a reliable manner.
