摘要： A method and a circuit are provided for the continuous detection of a line break in a full bridge controlling an inductive load. When the full bridge is switched off or on, a pre-determinable switching device of the circuit is switched first, and then a potential applied to a connection between the switching device and the load is tapped. The tapped potential is then compared with the ground potential when the switching device is connected to the supply potential, or with the supply potential when the switching device is connected to the ground potential. A line break is then determined when the two compared potentials are not different in the free running state thereof.

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 for controlling an inductive load, e.g. of a fuel injection valve, includes supply terminals for supplying a voltage, output terminals for connecting the load, and a detection device which is connected to at least one of the output terminals and is used for detecting the point in time at which the operation of the load is discontinued and/or detecting at least one fault case during a non-operational phase of the load. In order to render the detection process more reliable while using less circuitry, the detection device encompasses a current mirror with a first current source and a second current source. The current first is connected to one of the two output terminals during a detection phase. The current supplied by the second current source is evaluated as a signal of the detected result.
