STMicro dSPIN Microstepping Motor Driver

STMicroelectronics L6470 dSPIN*
Fully Integrated Microstepper Motor Driver

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.
