AMIS-30512  
Micro-Stepping Motor Driver  
Introduction  
The AMIS30512 is a microstepping 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 onchip  
voltage regulator, resetoutput and watchdog reset, able to supply  
peripheral devices. The AMIS30512 contains a currenttranslation  
table and takes the next microstep 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 socalled “speed and load angle”  
output. This allows the creation of stall detection algorithms and  
control loops based on loadangle to adjust torque and speed. It is  
using a proprietary PWM algorithm for reliable current control.  
The AMIS30512 is implemented in I2T100 technology, enabling  
both highvoltage analog circuitry and digital functionality on the  
same chip. The chip is fully compatible with the automotive voltage  
requirements.
