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 RDSon 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
protections. 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, dead time, PWM
frequency etc.) are sent through a standard
5Mbit/s SPI.
A very rich set of protections (thermal, low bus
voltage, overcurrent, motor stall) allows designing
a fully protected application, as required by most
demanding motor control applications.
