Description
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
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
register set.

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.
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.
