The EVL6480 is a stepper motor driver evaluation board based on the L6480.

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

The L6480 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 full bridge gate driver for N-channel MOSFET power stages with embedded non-dissipative overcurrent protection. Thanks to a unique voltage driving mode, which compensates for BEMF, bus voltage, and motor winding variations, the microstepping of a true 1/128-step resolution is achieved. 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 protection trip point, dead time, PWM frequency, etc.) are sent through a standard 5-Mbit/s SPI. A complete set of protections (thermal, low bus voltage, overcurrent, and motor stall) makes the L6480 device "bullet proof," as required by the most demanding motor control applications.Read more
