Abstract
A motor control circuit for controlling a motor, the circuit comprising a switched mode power supply operable to drive a full bridge switching transistor arrangement and to provide a stable voltage to the motor control circuit, wherein the switching transistor arrangement is connectable to the windings of the motor to be controlled, and wherein the switching transistor arrangement comprises: a first set of transistors in an upper part of the full bridge and a second set of transistors in a lower part of the full bridge, the first set of transistors being driven by a first output of the switched mode power supply and the second set of transistors being driven by a second output of the switched mode power supply.
