摘要： A circuit includes a switching unit, a switching element, and a control unit. The control unit provides at least one supply signal depending on a switching position of the switching element. An advance signal and the supply signal(s) of the control unit are assigned to the switching unit on the input side. The switching unit supplies and controls predetermined components of the switching unit, which are configured to control the switching element in accordance with the advance signal in such a way that the components activate the switching element. The switching unit is also configured to detect the supply signal(s) present once the switching element has been activated and in response thereto to switch to supplying the predetermined components by way of the supply signal(s).

摘要： A driver chip for driving an inductive load and a module having a driver chip are provided. The driver chip contains a first transistor for coupling a first potential to a first output and a second transistor for coupling a second potential to the first output. A first protection circuit reduces an increased voltage between a control terminal and a load junction terminal of the first transistor. The driver chip has a first state in which the second transistor is turned off and the first transistor can switch a passive inductive load connected to the output. In a second state, the first transistor and the second transistor can switch an external power transistor connected to the first output. A second output is connected to a load junction terminal of the external power transistor. A second protection circuit reduces an increased voltage between the first and second outputs.

摘要： A circuit configuration includes an output stage having at least one inductive load and a switching transistor configuration for switching the at least one inductive load. A supply voltage has a first supply potential and a second supply potential for feeding the supply voltage to the output stage. A registering device registers a particular instance when a potential at a specific circuit node of the output stage is outside a potential range defined by the first and second supply potentials.
