Abstract
A device for regulating a voltage drop across a load, particularly an electromagnetic load, includes an actuator connected in series with the load, a ground and a supply voltage. A first current balancing circuit provides an actual current which corresponds to the voltage across the load. A current source establishes a desired current. A second current balancing circuit provides a signal for actuation of the actuator as a function of a comparison of the actual current with the desired current, the actuator thereby regulating the voltage across the load.
