An apparatus is described for regulating the flow of current through a load in which the flow of current is monitored in the form of a reference voltage by an analog input and a digital input of an arithmetic and logic unit. The voltage measured at the analog input is used to regulate the flow of current. The voltage measured at the digital input either as a low or as a high signal is used to switch off the flow of current when there is a low signal.
[We claim:] [1.]a measurement line connecting a load to ground;a current source connected to said measurement line and to an output line, said current source outputting a current onto said output line in dependence on a voltage on said measurement line;an arithmetic and logic unit having an analog input and a digital input each connected to said output line;a switch connected to said arithmetic and logic unit;said arithmetic and logic unit determining a value of the voltage on said output line via said analog input and, depending on the voltage determine...
