dSPIN fully integrated microstepping motor driver

with motion engine and SPI

Features

■ Operating voltage: 8 - 45 V

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

■ Low R_DSonpower MOSFETs

■ Programmable speed profile

■ Programmable Power MOSFET slew rate

■ Up to 1/16 microstepping

HTSSOP28

POWERSO36

All application commands and data registers,

including those used to set analog values (i.e.

current control value, current protection trip point,

dead time, etc.) are sent through a standard 5-

Mbit/s SPI.

■ Predictive current control with adaptive decay

■ Non-dissipative current sensing

■ SPI interface

■ Low quiescent and standby currents

■ Programmable non-dissipative overcurrent

A very rich set of protections (thermal, low bus

voltage, overcurrent) makes the L6472 “bullet

proof”, as required by the most demanding motor

control applications.

protection on all Power MOSFETs

■ Two levels of overtemperature protection

Description

Tape and reel

Tube

The L6472, realized in 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 R_DS(on)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. 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, easily programmed through a dedicated
