AMIS-30521 - Micro-Stepping Motor Driver
AMIS-30521, NCV70521 Micro-Stepping Motor Driver 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.
