Abstract
A monitoring system for monitoring a supply voltage for an electronic component is described, comprising a voltage monitoring unit, which is configured to monitor a voltage level assigned to a supply voltage applied to the electronic component, and a switching unit which is configured to switch the electronic component on and/or off. The switching unit is coupled with the voltage monitoring unit. The switching unit is furthermore configured to switch off the electronic component if the voltage monitoring unit determines that the voltage level is below a predetermined threshold value. A mains monitoring circuit is furthermore described.
