NCV70516

Micro-stepping Motor Driver

Description

The NCV70516 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 NCV70516 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 an electrical error, an under−voltage or an elevated junction

temperature is detected. It is using a proprietary PWM algorithm

for reliable current control.

MARKING

DIAGRAMS

NCV70516 is fully compatible with the automotive voltage

requirements and is ideally suited for general−purpose stepper motor

applications in the automotive, industrial, medical, and marine

environment.

Due to the technology, the device is especially suited for use

in applications with fluctuating battery supplies.
