Introduction

http://onsemi.com

PINOUT

The AMIS−30521/NCV70521 is a micro−stepping stepper motor

driver for bipolar stepper motors. The chip is connected through I/O

pins and a SPI interface with an external microcontroller. The

AMIS−30521/NCV70521 contains a current−translation table. It 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 521 is ideally suited for general purpose stepper motor

applications in the automotive, industrial, medical and marine

environment. The AMIS−30521 is intended for use in industrial

applications. The NCV70521 version is qualified for use in

automotive applications.
