A motor bridge driver integrated circuit comprises a first set of input ports arranged to receive control signals from a first microprocessor, a second set of input ports arranged to receive control signals from a second microprocessor, and at least one set of output ports arranged to output motor phase switching signals to the switches of a motor bridge. A diagnostic circuit receives and monitors the control signals received from the two microprocessors and from those signals determines which microprocessor is to be treated as a master and which is to be treated as a slave at any given time by the motor bridge driver. An arbitration circuit selectively enables only the master microprocessor to the take control of the motor bridge at any given time while preventing the slave microprocessor from taking control of the motor bridge.
