EVAL6472H-DISC: fully integrated stepper motor driver based on
the L6472 and STM32™
Introduction
The EVAL6472H-DISC can be used together with the STM32™ firmware library V1.0 and
constitutes a complete motor control evaluation and a development platform.
It is a demonstration board for motor control applications in the range of 8 V to 45 V of DC
bus voltage using the STM32F105RB microcontroller with an internal 128 kB Flash size and
a 64 kB internal RAM and the L6472 fully integrated solution suitable for driving two-phase
bipolar stepper motors up to 1/16 microstepping.
The L6472 device integrates a dual DMOS full bridge with all of the power switches
equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative
current control and overcurrent protection.
With dedicated hardware evaluation features, the EVAL6472H-DISC board is designed to
help developers evaluate the device and develop their own applications.
