Estimating the term…
The protection circuit serves for the monitoring of output voltages of a power supply unit which has a normal mode and a standby mode. The protection circuit has here a first switching stage, coupled to the current input of which are output voltages which are present both in the normal mode and in the standby mode and coupled to the control input of which are output voltages which are only present in the normal mode. A control signal, by which for example the power supply unit is switched over between normal mode and standby mode, is coupled to the control input of this switching stage. As a result, by means of the control signal, the output voltages which are only present in the normal mode are blocked in the standby mode by the control signal, so that in the standby mode only the output voltages which are coupled to the current input are monitored.
A protection circuit with a first switching stage for the monitoring of output voltages of a power supply unit which has a normal mode and a standby mode, wherein coupled to a current input of the switching stage are output voltages which are present both in the normal mode and in the standby mode, and in that coupled to a control input of the switching stage are output voltages which are only present in the normal mode.
