AMIS-30532
Micro-Stepping Motor Driver
Introduction The AMIS−30532 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. The AMIS−30532 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 torque and speed. It is using a proprietary PWM algorithm for reliable current control.
