| description | bbA current-limiting circuit, which limits an electrical current from a voltage source to a consumer to a predetermined maximum current. A measuring resistor is coupled into a current lead between a circuit input and a circuit output. A transistor of the circuit is coupled into the current lead with its collector-emitter path in series with the measuring resistor, and its base is connected to the current lead through a series resistor. A shunt regulator of the circuit has an anode, a reference input and a cathode, wherein the cathode is connected to the base of the transistor, and the anode and the reference input form a voltage tap across the measuring resistor. An additional, high-ohmic current path extends in parallel to the transistor and includes a component connected reverse-biased having a diode characteristic and an auxiliary measuring resistor, wherein the auxiliary measuring resistor is integrated in the voltage tap. |
