    • The present invention relates to an open drain input/output structure and manufacturing method thereof in which a n-channel depletion transistor for pull-up resistance can be used like an enhancement transistor without impurity ion implantation process when being formed an open drain input/output terminal. An open drain input/output structure in a semiconductor device according to the present invention includes: a gate formed with an enhancement transistor at a predetermined portion on a first conductive-type semiconductor substrate which is formed with a gate insulating layer; a second conductive-type source/drain region formed in the semiconductor substrate at the both sides of the gate; and a second conductive-type impurity implantation region formed at a predetermined portion of a channel region at the lower part of the gate so as to selectively connected to the source region or the drain region. Therefore, according to the present invention, because the gate length of a n-channel depletion transistor is designed to have longer than conventional ones' so as to changed a depletion transistor into an enhancement transistor there is no necessary an impurity ion implantation process after gate forming process when an open drain I/O is achieved. Therefore, all a pull-up resistance I/O and an open drain I/O of a mask ROM embedded MCU, EPROM embedded MCU can be achieved with the same lay out structure thereby to be compatible when being manufactured MCU.

    • A motor control circuit comprises a current command circuit generates a current command signal proportional to a selected motor speed. A comparator generates a comparator output signal proportional to the difference between the current command signal and a signal proportional to current flow in the motor. An output terminal of the comparator is operatively connected to a logic circuit which generates a control signal having a duty cycle that varies proportional to the comparator output signal. A drive circuit has an input terminal to which the control signal is applied and an output terminal connected to the motor. The drive circuit generates a motor drive signal proportional to the control signal for driving said motor. A current command control circuit has an input terminal to which the current control signal is applied and an output terminal to which the current command signal is applied. The current command control circuit generates a signal proportional to the control signal and reduces the current command signal when the proportional signal is less than the current command signal.
