AMIS-30542 Micro-Stepping Motor Driver Introduction The AMIS 30542 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. It has an on chip voltage regulator, reset output and watchdog reset, able to supply peripheral devices. AMIS 30542 contains a current translation table and takes the next micro step depending on the clock signal o.
