Evaluation and Demonstration Boards and Kits

The DRV8303EVM motor driver evaluation and demonstration board (EVm) facilitates evaluation of the DRV8303EVM motor driver with Resolver feedback. It is a great tool for making quick transitions from customer design to fully functional motor control system. This device has a wide range of applications in automotive, robotics, aerospace, medical, and industrial performance solutions.

Applications

The DRV8303EVM supports one or two independent 3-phase brushless DC motors, each with separate driver circuits. This EVM is designed to evaluate the DRV8303EVM family of motor drivers using a Resolver input for sensing angular position. Through the Resolver interface, the DRV8303EVM is able to communicate with the DRV8303ESD which in turn communicates to the MCU with four wires. The EN/FAULT contributions to the audible or residual noise of a sensored motor are also minimized due to the integrated digital filtering.

The DRV8303EVM driver can easily be used in applications that require motion control such as synchronizing or tracking of multiple mechanical devices. This EVM is well suited for palletizing and packaging systems, unmanned vehicles, automated assembly, and rotary indexing dials as well as a wide range of industrial and entertainment applications.

Working Principle

The DRV8303EVM motor driver evaluation board operates on a 3-phase power bridge configuration with Resolver feedback. The DRV8303EVM driver operates in cycle-by-cycle current limiting mode. The DRV8303EVM driver board contains circuitry for sensing the angular position of the rotor through a Resolver interface. The angular position is used for calculating the phase currents of the motor and generating the drive signals.

The DRV8303EVM uses the Resolver signals to produce very precise angular position information required for many motion control applications. The DRV8303EVM driver is able to detect motor back-EMF for better motor commutation timing. It can also detect the load current for the limit the current that is drawn from the power supply. These features provide an optimized design for efficient current delivery to minimize heating and power consumption.

The DRV8303EVM motor driver evaluation board also provides diagnostic features such as power-on reset, brown-out detection, cycle-by-cycle current limiting, and under-voltage lockout. The DRV8303EVM also uses fault indication signals that are available to the application. This capability enables troubleshooting of motor control systems in a cost-effective and safe way.
