Introduction

PINOUT  
The AMIS30521/NCV70521 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. The  
AMIS30521/NCV70521 contains a currenttranslation table. It 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 AMIS30521/NCV70521 is implemented in I T100  
ERR  
technology, enabling both high voltage analog circuitry and digital  
functionality on the same chip. The chip is fully compatible with the  
automotive voltage requirements.

The 521 is ideally suited for general purpose stepper motor  
applications in the automotive, industrial, medical and marine  
environment. The AMIS30521 is intended for use in industrial  
applications. The NCV70521 version is qualified for use in  
automotive applications.
