Product overview

Description

The EVL6472 is a stepper motor driver evaluation board based on the L6472.

It provides an affordable and easy-to-use solution to drive a stepper motor in your application.

The L6472 device, created using analog mixed signal technology, is an advanced, fully integrated solution suitable for driving two-phase bipolar stepper motors with microstepping. It integrates a dual low RdsON DMOS full bridge with an accurate on-chip current sensing circuitry suitable for non dissipative current control and overcurrent protection. Thanks to a new current control, a 1/16-microstepping is achieved through an adaptive decay mode which outperforms traditional implementations. The digital control core can generate user-defined motion profiles with acceleration, deceleration, speed, or target position, which are easily programmed through a dedicated set of registers. All application commands and data registers, including those used to set analog values (that is: current control value, current protection trip point, dead time, etc.) are sent through a standard 5-Mbit/s SPI.A complete set of protections (thermal, low bus voltage and overcurrent) makes the L6472 device “bullet proof”, as required by the most demanding motor control applications.

The EVL6472 is compatible with the Arduino® UNO R3 connector, and it supports the addition of other boards, which can be stacked to drive up to three stepper motors.
