DRV8662EVM is a evaluation and demonstration board and kit developed and released by Texas Instruments. This kit helps in evaluating the DRV8662 dual-channel motor driver and its devices by providing a platform for evaluating the performance. By using this kit, one can quickly design and evaluate the system-level performance of an application.

The DRV8662EVM board includes two drivers, four motor ports, a 24-V node, adjustable braking, adjustable current sensing, and a real-time current feedback. It also supports PC-controlled diagnostics through the GPIB interface.

The DRV8662EVM application field is mainly used to control two DC or brushless DC motors in multiple configurations and operation modes, and to drive motors with various properties. It can be used for robotic and industrial motor control applications, electric drive control applications, and other applications where high-current, high-voltage motor control is needed.

The working principle of the DRV8662EVM kit is one of the methods of driving two motors with one master and one slave driver. The master driver is used to select the phase of current waveforms, control the direction of the motor, and adjust the speed of the motor. Meanwhile, the slave driver will control the current of the motor by its current control function. The current control function can help to reduce the power consumption and enhance the system efficiency.

To work with this EVM, an external variable power supply is recommended to power the devices. First, the evaluation board should be powered up and then the DRV8662 drivers can be programmed through an interface such as the Serial Peripheral Interface (SPI). The communication between the master and the slave allows for high-performance motor controls without the need of external microcontrollers.

Once the DRV8662EVM is set up, it can be used to analyze the performance of the motor and provide performance feedback in real-time. Users can use the current sense pins to observe the motor performance without the need for additional circuitry.

Overall, the DRV8662EVM is a versatile platform for evaluating the performance of two motors with one master and one slave driver. It provides an efficient way for motor control and enables users to develop and evaluate their system-level motor control application.
