Overview
...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 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.
The AMIS−30542 is implement...
