Driver

Introduction

NCV70501 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. The NCV70501 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 an error message if

stall, an electrical error or an elevated junction temperature is detected.

It is using a proprietary PWM algorithm for reliable current control.

NCV70501 is fully compatible with the automotive voltage

requirements and is ideally suited for general−purpose low current

range stepper motor applications in the automotive, industrial,

medical, and marine environment.
