Datasheet Download
Overview
MS41968 is a low-voltage 5V multi-channel lens driver chip, integrated Hall mode aperture driver, quad channel stepper motor driver, dual channel DC motor driver and quad channel LED driver. In the driving part of the stepper motor, the voltage driving mode with current Microsteps and torque ripple correction technology are adopted to realize the ultra-low noise Microsteps motor drive. The MS41968 integrated logic IO interface power supply VIO, can be applied to different voltage interface 1.2V to 3.6V.
