Micro-Stepping Motor Driver
Introduction The NCV70522MN is a micro- stepping stepper motor driver for bipolar stepper motors. The chip is connected through I/O pins and a SPI interface with an external microcontroller. The NCV70522MN Features an internal current- translation table: it takes the next micro- step depending on the clock signal on the stepping input pin (NXT) and the status of the direction register or input pin (DIR). A reliable current control is achieved using an integrated proprietary PWM algorithm.
The NCV70522MN includes a so- called “Speed and Load Angle” (SLA) output, allowing the creation of stall detection algorithms and control loops to adjust torque and...
