Abstract
Upon receipt of a reference voltage signal Vi and a multiplicity of logic control signals L and L , the loading drive system converts the signals received into a first control voltage Vi and a second control voltage Vi in such that the voltage difference between the two logic control signals L1 and L represents the reference voltage signal, and the polarity of the difference represents the logic control signals. When the first and the second control voltages Vi and Vi are below a predetermined level, the one lower than the predetermined level is converted to zero Volt, and then the differences Vi −Vi and Vi −Vi are formed to define a first and a second output voltages, Vo and Vo , respectively. Thus, the logic control signals and the reference voltage signal can be supplied from the controller to the loading driver by a fewer number of signal lines, and so are input and output terminals or pins associated with the signals.
