L6474

easySPIN – fully integrated microstepping motor driver

Features

■ Operating voltage: 8 - 45 V

■ 7.0 A output peak current (3.0 A r.m.s.)

■ Low RDSon power MOSFETS

■ Programmable power MOS slew-rate

■ Up to 1/16 microstepping

■ Current control with adaptive decay

■ Non dissipative current sensing

■ SPI interface

■ Low quiescent and standby currents

■ Programmable non dissipative overcurrent

protection on all power MOS

■ Two-level overtemperature protection

Application

■ Bipolar stepper motor

Description

The L6474, realized in analog mixed signal

technology, integrates a dual low RDSon DMOS

full bridge with all power switches equipped with

an accurate on-chip current sensing circuitry

suitable for non dissipative current control and

overcurrent protections. Thanks to a new current

control, a 1/16 microstepping is achieved through

an adaptive decay mode which outperforms

traditional implementations.

All data registers, including those used to set

analogue values (i.e. current control value,

current protection trip point, dead time, etc.) are

sent through a standard 5 Mbit/s SPI.

A very rich set of protections (thermal, low bus

voltage, overcurrent) makes the L6474 “bullet

proof” as required by the most demanding motor

control applications.
