STMicroelectronics dSPIN Fully Integrated Microstepping Motor Driver
is realized in
analog mixed signal
technology, and is an advanced, fully integrated solution suitable for driving
two-phase bipolar stepper motors
with
microstepping
. The
STMicroelectronics dSPIN Fully Integrated Microstepping Motor Driver
integrates a
dual low R
DSon
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. A true 1/128 steps resolution is achieved thanks to a unique control system.
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 analog values (i.e. current control value, current protection trip point, dead time, 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 designing a fully protected application, as required by most demanding
motor control
applications.
