Working Principles

The L6228PD is a bipolar stepper motor driver that utilizes a combination of power MOSFETs and integrated circuitry to control the motor. It operates by receiving control signals from a microcontroller or other control device, which determine the direction and speed of the motor. The driver converts these control signals into appropriate voltage and current levels to drive the motor coils. By controlling the timing and sequence of these signals, the driver can accurately control the rotation and position of the stepper motor.
