MS41949 is a quad channel, low-voltage 5V stepper motor driver chip, which can drive four stepper motors. The ultra-low noise Microsteps motor drive is realized through the voltage drive mode with current Microsteps and torque ripple correction technology. A 5V DC motor driver is also built into the chip, and the sum of the resistors of the up and down switches is as low as 1Ω.
