EVAL6480H

High power stepper motor driver mounting the L6480

Data brief

Features Voltage range from 10.5 V to 85 V

Low Rds(ON) MOSFETs in DPAK package

SPI with daisy chain feature

FLAG and BUSY LED indicators

Adjustable supply voltage compensation

Flexible supply voltage management

Suitable for use in combination with the STEVAL-PCC009V2

Applications High power bipolar stepper motor driving

DescriptionThe EVAL6480H demonstration board is a high power microstepping motor driver. In combination with the STEVAL-PCC009V2 communication board and the evaluation software, the board allows the user to investigate all the features of the L6480 device. In particular, the board can be used to check the voltage mode driving and to regulate the L6480 parameters in order to fit the application requirements.

The EVAL6480H supports the daisy chain configuration making it suitable for the evaluation of the L6480 in multi-motor applications.
