Abstract
A protection circuit for protecting an electronic circuit against EMC disturbances and/or negative transient overvoltage pulses comprises a switch in series between a power supply and the electronic circuit to be protected; a comparator for comparing a first operating parameter with a second operating parameter and producing a comparison signal, the comparison signal being used as a control signal for controlling opening and closing of the switch; and a delay circuit adapted for delaying closing of the switch. A corresponding method is also provided.
