  • Semiconductor device, motor control device, lens unit for imaging apparatus, and imaging apparatus
    Patent number: 10082785
    Abstract: A motor control, device that controls a motor, includes: a plurality of processors, each being adapted to generate information for generating a pulse width modulation (PWM) signal; a plurality of PWM signal generation circuits, each being provided corresponding to each of the processors and adapted to generate the PWM signal on the basis of the information that has been generated by the corresponding processor; and a switch circuit that selectively gives the information generated by each of the processors to any of the PWM signal generation circuits.
    Type: Grant
    Filed: June 8, 2017
    Date of Patent: September 25, 2018
    Assignee: RENESAS ELECTRONICS CORPORATION
    Inventor: Shigeyuki Endo

  • Semiconductor device, motor control device, lens unit for imaging apparatus, and imaging apparatus
    Patent number: 9684300
    Abstract: In a motor control device, a matrix circuit and logic circuits are arranged between PWM signal generation circuits and output terminals. It is possible to output PWM signals to the output terminals as they are and to synchronize the PWM signals and output a synchronized signal to a desired output terminal/terminals in the output terminals by changing a coupled state of the matrix circuit. Therefore, it is possible to change the kind of the motor to be controlled, the number of motors to be controlled and so forth without changing the motor control device.
