The BD7964FS-E2 is part of a family of motor drivers, controllers, and high-voltage power management integrated circuits (PMICs) designed to support a wide range of applications. The BD7964FS-E2 is a dual-channel, peak-current-mode, single-phase stepping motor driver. It is designed to provide efficient, accurate, and reliable control of automotive or industrial systems that involve high-speed or high-power motors.

Application Field

The BD7964FS-E2 is a flexible motor driver that can be used in a variety of motor applications ranging from automotive to industrial purposes. It is capable of driving on-axis or off-axis single-phase, bipolar Stepping Motors in formats such as open-loop, closed-loop, position control, sinusoidal control and more. It supports a wide variety of motor types from small motor to high-power motors with full torque control. The BD7964FS-E2 also offers a unique feature for applications that require the motor to synchronize its speed with another motor or a machine, allowing multiple motors to work simultaneously.

The BD7964FS-E2 is suitable for robotics applications, 3D printers, power tools, precision positioning of automatic machines and other applications that require precise motor control. Additionally, it is designed to support automotive applications such as e-powertrain and autonomous driving as well as industrial automation and machine control. It is capable of providing precise control of motors in a wide range of conditions, making it ideal for applications that require long-term precise motion control.

Working Principle

The BD7964FS-E2 is a peak-current-mode, single-phase stepping motor driver. The current is controlled by a comparator that measures the current in the driver’s outputs and controls it by generating a proportional switching signal. The comparator also has a “dead-time” to avoid transient current exceeding its specified threshold.

The BD7964FS-E2 supports two driving modes: Controlling the speed by adjusting the duty cycle and Controlling the current by setting the peak current. The speed control mode is suitable for applications where quick acceleration and a wide speed range are required, such as autonomous driving and robotic applications. The current control mode is suitable for applications that require high accuracy and precise control of the motor, such as precision positioning and machine control.

The BD7964FS-E2 also supports current reduction function that can be used to reduce the current in the motor. This can be useful for noise reduction and high-power motor applications. Furthermore, the motor can be synchronized with other motors with the aid of the dead time compensation function. This synchronized operation ensures accurate synchronization of motors for solving complex machine control problems.

The BD7964FS-E2 also includes several protective features such as Motor Overtemperature Protection and Overload Protection. The Motor Overtemperature Protection stops the motor if the temperature exceeds its admissible range, protecting the motor from overheat damage. The Overload Protection stops the motor if the load exceed its admissible range, preventing damage to the motor and the driver.

Overall, the BD7964FS-E2 is a powerful and versatile motor driver that offers high-performance, accurate, and reliable control of a variety of motor applications. It is designed to support a wide range of motor types and provide precise and flexible motion control. The BD7964FS-E2 is an ideal solution for applications that require fast operation and precise motor control.
