Selecting the right motor driver is crucial to achieving the required functionality and performance for a given application. In addition to parameters such as voltage and output current, other key factors depend on not just the type of motor selected, but its intended application.

Brushed dc motors usually require a reversible driver and often need pulse-width-modulation (PWM), brake, and forward/reverse modes. Ideally, a motor driver for a brushed dc motor should also include a current-limiting function and may need to support a high-speed drive.
