ABSTRACT:
A control circuit is disclosed for switching current through a load impedance coupled in a bridge across two output terminals. The circuit comprises two power amplifiers, each power amplifier having a first and a second stage. The two power amplifiers are switched by an input stage which, depending on the level of a logic control signal, turns on the first stage of one of the two amplifiers and permits turning on of the second stage of the other amplifier. The second stage is alternately turned on and turned off by a regulating circuit. The first stage of each amplifier comprises two diodes interconnected in series in opposite directions of conduction and having their common terminal coupled to the input terminal of the first stage. This configuration substantially reduces the power dissipated by the first stage when the second stage of the other amplifier is turned off by the regulating circuit.
