The DRV8833CEVM is a comprehensive tool that is necessary to gain an understanding of the inner workings of a stepper motor driver, its features and performance. Evaluation and demonstration kits are available that can simulate the full range of functions and operation of the stepper motor driver. A detailed description of the application field and working principle of the DRV8833CEVM will be provided below.

Application Field

The DRV8833CEVM is designed to provide an evaluation platform and provide guidance when implementing stepper motor control applications. It can be used to evaluate and demonstrate various features and performance of a stepper motor driver. This evaluation platform provides a solution to display the stepper motor as well as other possible applications of a stepper motor.

Working Principle

The DRV8833CEVM is suitable for driving two-phase stepper motors with bipolar windings. This stepper motor driver uses a direct BEMF demodulation logic and the supplied voltage from the battery. The DRV8833CEVM includes a calibrated current sense amplifier and constant current limiter for each of the stepper motor’s control winding as a protection method. The motor control is done by using the six-pin DRV8841CEVM jumpers, which can be used to change the stepper motor’s direction of rotation. The DRV8833CEVM would allow to supply a stepper motor with the most suitable performance profile.

The DRV8833CEVM is designed to be used with an external microcontroller to enable real-time control of a stepper motor. The evaluation board has three Vref jumpers for fine current control tuning, and a three-state profile switch for rapid profile selection. Furthermore, the evaluation board also includes a DC motor control interface, an LED driver with strobe inputs for fault diagnostics, and a 5-pin debugging interface.
