L6470  
dSPIN fully integrated microstepping motor driver with motion  
engine and SPI  
Datasheet production data  
Features  
Operating voltage: 8 - 45 V  
7.0 A out peak current (3.0 A r.m.s.)  
Low RDS(on) Power MOSFETs  
Programmable speed profile and positioning  
Programmable power MOS slew rate  
Up to 1/128 microstepping  
POWERSO36  
HTSSOP28  
Sensorless stall detection  
power switches equipped with an accurate on-  
chip current sensing circuitry suitable for non-  
dissipative current control and overcurrent  
protection. Thanks to a unique control system, a  
true 1/128 steps resolution is achieved. The  
digital control core can generate user defined  
motion profiles with acceleration, deceleration,  
speed or target position, easily programmed  
through a dedicated registers set. All commands  
and data registers, including those used to set  
analogue values (i.e. current control value,  
current protection trip point, deadtime, PWM  
frequency, etc.) are sent through a standard 5-  
Mbit/s SPI. A very rich set of protections (thermal,  
low bus voltage, overcurrent, motor stall) allows  
the design of a fully protected application, as  
required by the most demanding motor control  
applications.  
SPI interface  
Low quiescent and standby currents  
Programmable non-dissipative overcurrent  
protection on high and low-side  
Two levels of overtemperature protection  
Application  
Bipolar stepper motors  
Description  
The L6470, 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 RDS(on) DMOS full bridge with all of the  
Table 1.
