Abstract:
A circuit for driving multiple load elements comprising:a first reference voltage terminal; a second reference voltage terminal; a first switch having an output terminal for communication with a first terminal of a first load device; a second switch having an output terminal for communication with a second terminal of said first load device and a first terminal of a second load device; a third switch having an output terminal for communication with a second terminal of said second load device; a first control switch in electrical communication with said first switch, said first control switch receiving a first control signal and a second control signal and providing one of said first control signal and said second control signal; and a second control switch in electrical communication with said third switch, said second control switch providing one of said first control signal and said second control signal, wherein said output terminal of said first switch is coupled to said first reference voltage terminal when said first control signal is in a first state and wherein said output terminal of said first switch is coupled to said second reference voltage terminal when said first control signal is in a second state, and wherein said output terminal of said third switch is coupled to said first reference voltage terminal when said second control signal is in a first state and wherein said output terminal of said third switch is coupled to said second reference voltage terminal when said second control signal is in a second state.
