Abstract: There is provided a controller for a DC motor drive transistor which controls a parameter of a motor, the transistor being of PNP or NPN type, and the controller comprising a detection circuit, adapted to determine whether the DC motor drive transistor is of the PNP or NPN type and a driver circuit, adapted to sink current from the PNP transistor if it is determined that a PNP transistor is present, or source current into the NPN transistor if it is determined that an NPN transistor is present.
