Abstract: A circuit 1 includes a bipolar junction transistor (BJT) 10 having a collector drift region, a controller 30, and a driver circuit 20 receiving a control signal from the controller and connected at its output to a base terminal of the BJT. The driver circuit provides a tri-state output and switches in response to the control signal between an ON state to switch the transistor ON, an OFF state to switch the transistor OFF, and a floating state. The controller operates the driver circuit to set the output in the floating state for longer than it is in the ON state and/or the OFF state within an ON/OFF switching cycle. The circuit may include a bypass connection with a resistive load 40 selected to decay charge in the drift region whilst the transistor is ON to reduce the switching time of the BJT. A motor driver (Fig.5, 1000) for a multi-phase electric-motor includes a switching circuit having multiple BJTs (Fig.5, 100) for switching current through the motor windings (Fig.5, 500A), each BJT having a collector drift region and being associated with a separate tri-state driver circuit (Fig.5, 200).
