Introduction
The AMIS−30521/NCV70521 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 AMIS−30521/NCV70521 contains a current−translation table. It takes the next micro−step depending on the clock signal on the “NXT” input pin and the status of the “DIR” (= direction) register or input pin. The chip provides a so−called “Speed and Load Angle” output. This allows the creation of stall detection algorithms and control loops based on load−angle to adjust torque and speed. It is using a proprietary PWM algorithm for reliable current control.
