AMIS-30522 Micro-Stepping Motor Driver

AMIS-30522, NCV70522 Micro-Stepping Motor Driver Introduction The AMIS 30522/NCV70522 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 30522/NCV70522 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. Th.
