L6470PDTR Fully integrated microstepping motor driver with motion engine and SPI PowerSO-36 Slug Up spot stock

    Product Descriptions

The L6470 device, 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  power switches equipped with an accurate onchip current sensing circuitry suitable for nondissipative 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.
