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 RdsONDMOS 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.Read more
