Description

The powerSTEP01 is a a system-in-package

integrating 8 N-channel 16 mΩ MOSFETs for

stepper applications up to 85 V with a SPI

programmable controller, providing fully digital

control of the motion through a speed profile

generation and positioning calculations.

It integrates a dual low RDS(on) full bridge with

embedded non-dissipative overcurrent protection.

The device can operate with both voltage mode

driving and advanced current control fitting

different application needs. The digital control

core can generate user defined motion profiles

with acceleration, deceleration, speed or a 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.
