The MC33689DWBR2 is an integrated circuit of a high voltage, high current motor driver solution that enables cost-effective solutions to controlling medium to high power motors. It is designed as a total solution, combining a driver and a power transistor array, which are usually implemented separately.

The MC33689DWBR2 is suitable for controlling brush DC and permanent magnet DC motors with up to 36V and 10A motor currents, in addition to three-phase, brushless DC motors with up to 12A output current. This total motor driver solution is optimized for smooth and efficient control of the motor torque and speed, providing up to 45% peak power savings during motor operation, as well as improved overall system efficiency.

The device can be easily integrated in any application that requires motor control, such as automotive and industrial control tools, consumer massagers, robotic toys and robotics applications, appliances, and motion control. The MC33689DWBR2 can also be used in embedded systems, as well as in communications and entertainment products.

The MC33689DWBR2 works by providing a high voltage, high current capability, as well as a configurable timer. The timer helps provide accurate control, while the voltage and current provide the power needed to adequately power the motor to the desired speeds and forces. The device also offers a temperature protection circuit, an internal voltage regulator, a power-on reset circuit, an over-current protection circuit and a current limiting circuit.

The MC33689DWBR2 also includes an embedded analog front end that offers up to 10A peak current and up to 36V peak voltage, enabling efficient control over a wide range of motors. This device also offers a flexible interface, which allows for simple setup and configuration of the motor driving data, including upping and downing of the motor speed.

The embedded analog front end also includes an analog comparator, which can be used to detect faults in the motor control circuitry. Additionally, a clock oscillator is also included to allow for synchronization between the system and the motor.

The MC33689DWBR2 also supports serial programming, offering an SPI or I2C interface, depending on the application. UART is also available as an option. This makes it possible to create a robust, low-cost motor control system, with a limited amount of time spent in software development.

In addition, an on-chip motor fault monitor is available for monitoring the motor’s health and providing alerts when fault events occur. The monitor can be configured to generate alerts that can be used to safely shut down the motor and the system, when necessary.

In short, the MC33689DWBR2 is a total motor control solution, highlighting its impressive power efficiency, easy integration and wide range of features for controlling brush DC, permanent magnet DC and brushless DC motors. It is a great choice for various applications, providing a cost-effective, efficient and robust motor control solution.
