Fully integrated stepper motor driver

Datasheet

preliminary data

motor winding variations, the microstepping of a

true 1/128-step 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 register set. All application commands

and data registers, including those used to set

analog values (i.e. 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

and motor stall) make the powerSTEP01 “bullet

proof”, as required by the most demanding motor

control applications.

Description

The powerSTEP01 is a fully integrated solution

suitable for driving two-phase bipolar stepper

motors with microstepping.

It integrates a dual low R_DS(on)full-bridge with

embedded non-dissipative overcurrent protection.
