Evaluation and Demonstration Boards and Kits is one of the most important product lines of Texas Instruments. The DRV8843EVM is one of their products which is designed to evaluate the DRV8843 Dual Half-H Bridge Motor Driver. It is specially designed for motor control solutions with 1.2 A maximum output current per channel that supports higher brushed DC motor ratings than was previously possible.The DRV8843EVM can be used in many applications. Examples include portable motor control applications like cordless tools, robotic vacuums, model car components, cooling fans, etc. In such a context, the use of the DRV8843EVM makes the process of designing, testing, and prototyping much faster and easier.The DRV8843EVM comes with several features that help users understand the motor control principles at work and building a motor control application in a shorter amount of time. This includes an 8-pin jumper connector which allows users to connect to a microcontroller which can then be programmed using the Code Composer Studio and other open source software.The driver looks like a basic motor driver IC. It is based on two full H-Bridge integrated circuits which are specifically designed to drive motors with high efficiency. To increase the durability of the driver, Texas Instruments has included several protective features such as over-current and over-temperature shut down.The DRV8843EVM board consists of three main parts. The first part is the motor controller IC which is the heart of the board. The next part is the onboard programmable controller which helps control the motor driver’s parameters and generate necessary pulse width modulation (PWM) signals to control the motor’s speed and direction. The last part is the motor connector, which allows users to plug in a DC motor to be driven by the DRV8843EVM board.In addition to the DC motor, the DRV8843EVM supports the use of servo motors. However, due to the servo motor’s high battery consumption, the DRV8843EVM is designed to only accept 3.3 to 6 V of voltage.The DRV8843EVM is a complete solution for motor control applications that require high efficiency, small size, and cost-efficiency. It provides users with full access to the motor control features and parameters through its onboard controller and accompanying software. Furthermore, it is protected by various safety features which allows it to be used in multiple applications that require high reliability.
