Basic Low Voltage DC Servo Motor Control

This design is comprised of general components to control motors. The MC33932EK 5.0 A Throttle Control H-Bridge provide the DC load current that put the motor in operation. It has internal charge pump and gate drive circuitry that supports external PWM frequencies up to 11kHz. The FBA and FBB pins are analog feedback output that provides a constant-current source ratioed to the active high side MOSFETs current. The IN1 and IN2 provide the control of the two totem-pole half-bridge outputs. The D1 and EN/D2 are two independent disable inputs that forces the H-bridge outputs to a high-impedance state. The EN/ D2 pin also controls an enable function that allows the IC to be placed in a power-conserving sleep mode. The MCU act as the main controller and provide the ports that can be used to further developed the design. The motors are the output components that relies on the system command.

This is useful to industrial automation and control that it can make the system more efficient due to its body design and numerous operational features. The design can be build easily because it is straightforward that an ordinary hobbyist will be able to understand and make some experiment on it.
