Abstract:
The invention relates to an electric circuit configuration for switching an electrical load (3), particularly a solenoid valve, by means of at least one switching means (5) associated with the consumer (3), particularly a transistor. The circuit configuration comprises at least one analysis circuit comprising at least one measuring resistor (17) connected in series with the switching means (5), at least one first analysis means (23) for determining a parameter corresponding to the short-circuit current, and at least one second analysis means (25) for determining a parameter corresponding to the consumer current. The circuit configuration is characterized in that the first analysis means (23) is connected in parallel with the measurement resistor (17).
