MS41919 is a dual channel 5V low voltage stepper motor driver chip, through the current Microsteps voltage drive mode and torque ripple correction technology, to achieve ultra-low noise Microsteps drive. The chip also has a integrate DC motor driver, and the sum of the resistors of the up and down switches is as low as 1.1Ω.
