It supports three-phase motor drivers with variable current output and adjustable parameters. The board includes convenient expansion headers to connect other TI evaluation boards or external components.Application FieldsThe BOOSTXL-DRV8320S evaluation board is an ideal solution for motor control applications such as automotive, robotics, and home appliances. It provides a convenient and cost-effective platform to develop a motor driver system with adjustable parameters. The board is also suitable for applications such as vector control, adjustable current limit, and over-voltage monitoring.The board supports a wide range of motor types with different voltage levels, making it suitable for applications such as electric vehicles, industrial machinery, and solar pumps. Additionally, the board is compatible with multiple MCUs from TI’s portfolio, allowing users to tailor the driver system to their own needs.Working PrincipleThe BOOSTXL-DRV8320S evaluation board is based on the DRV8320S motor driver, which operates using a multi-mode system. It is designed to drive three-phase brushless DC (BLDC) motors in three different modes: current loop, voltage loop, and torque control.In current loop mode, the motor driver operates in a closed-loop system. It compares the actual motor current with the set current and makes adjustments to produce the required output. This mode is suitable for applications requiring precision control such as AC servo motors.In voltage loop mode, the motor driver operates in an open-loop system. It sets the motor voltage and adjusts the duty cycle accordingly to reach the desired motor speed. This mode is used in applications such as robotic motors where precise control is not needed.Finally, in torque control mode, the motor driver adjusts the output with torque demand as the setpoint instead of the motor speed. This mode is commonly used in robotics and other applications where precision is a requirement.ConclusionThe BOOSTXL-DRV8320S evaluation board is an easy-to-use solution for developers looking to quickly evaluate the DRV8320S motor driver. It enables users to evaluate and develop motor driver systems with adjustable current limits, over-voltage protection, and adjustable parameters. The board supports three-phase motors with variable current output, making it suitable for a wide range of industrial, automotive, and robotics applications.
