摘要： An apparatus and a method for recognizing an error in a power bridge circuit containing a load, a high-side branch and a low-side branch. Accordingly, a first switched current source is connected to the load and to a diagnosis connection for a high-potential of a diagnosis voltage, a second switched current source is connected to the load and to a diagnosis connection for a low-potential of the diagnosis voltage, and a control device for controlling the first switched current source and the second switched current source. The control device switches on one of the switched current sources when the high-side power switch and the low-side power switch are open, while the other switched current source is switched off. A testing device tests a voltage at the load when one of the switched current sources is switched on and the other of the switched current sources is switched off.

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.

摘要： A method for actuating a solenoid valve generates precise opening and closing times of the solenoid valve. To this end, an actuating current provided for actuating the solenoid valve and applied to an actuating coil of the solenoid valve is already reducing in a reduction phase prior to a switch-off point in time of the solenoid valve relative to a maintained level of the actuating current, at which the solenoid valve is reliably held in an actuating position.
