L6474PDTR Stepper Motor Drivers by STMicroelectronics

Stepper motor driver with up to 16 microsteps with SPI and advanced current control


The L6474 device, realized in analog mixed signal technology, integrates a dual low R DS(on) DMOS full bridge with all power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative current control and overcurrent protections. Thanks to a new current control, a 1/16 microstepping is achieved through an adaptive decay mode which outperforms traditional implementations. All data registers, including those used to set analogue values (i.e.: current control value, current protection trip point, deadtime, etc.) are sent through a standard 5 Mbit/s SPI. A very rich set of protections (thermal, low bus voltage, overcurrent) makes the L6474 device “bullet proof” as required by the most demanding motor control applications.
