Abstract

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.
