AMIS-30543 Micro-Stepping Motor Driver Introduction The AMIS 30543 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. It has an on chip voltage regulator, reset output and watchdog reset, able to supply peripheral devices. AMIS 30543 contains a current translation table and takes the next micro step depending on the clock signal .
