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 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” output.
This allows the creation of stall detection algorithms and control loops based on load−angle to adjust torqu...
