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 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 triggering an electromagnetic consumer with low coil resistance (solenoid for a Diesel injection pump) having a free-running circuit that can be switched over, and an apparatus for performing the method, regulate a voltage at an end stage to a predetermined value. This is accomplished by controlling the control voltage of the end stage during a turn-on phase until a turn-on peak current is reached and then regulating the holding current by repeatedly lowering the current through the end stage and keeping it constant to a predetermined value during a predetermined time period and then raising it again to a maximum value of the holding current until the consumer is turned off.

摘要： An apparatus for switching an inductive load includes a MOSFET switch and provides for limiting a voltage across the load during switching-off of the latter. One or two clamping circuits are used without zener diodes and with different, temperature-independent clamping voltages for the purpose of rapid demagnetization of the load in a constant demagnetization time.
