Working Principles

The MP6500GU-P is a motor driver IC designed to control and drive stepper motors. It utilizes a combination of pulse width modulation (PWM) and current control techniques to accurately position the motor shaft. The driver receives step and direction signals from a microcontroller or other control circuitry, and converts them into appropriate current levels to drive the motor coils. By controlling the timing and magnitude of these currents, the driver can precisely move the motor in small increments, resulting in smooth and accurate motion.
