AMIS-30521 Micro-stepping Motor Driver Data Sheet 1.0 Introduction The AMIS-30521 is a micro-stepping stepper motor driver for bipolar stepper motors.
The chip is connected through I/O pins and an SPI interface with an external microcontroller.
The AMIS-30521 contains a current-translation table and 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” o
