摘要:
Disclosed is an electronic circuit. The electronic circuit includes a transistor having a control terminal to receive a drive signal, and a load path between a first and a second load terminal. A voltage protection circuit is coupled to the transistor, has a control input, is configured to assume one of an activated state and a deactivated state as an operation state dependent on a control signal received at the control input, and is configured to limit a voltage between the load terminals or between one of the load terminals and the control terminal. A control circuit is coupled to the control input of the voltage protection circuit and is configured to deactivate the voltage protection circuit dependent on at least one operation parameter of the transistor and when a voltage across the load path or a load current through the load path is other than zero.
