Description
The powerSTEP01 is a system-in-package
integrating 8 N-channel 16 mΩ MOSFETs for
stepper applications up to 85 V with an SPI
programmable controller, providing a full 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’s 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, 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
and motor stall) make the powerSTEP01 “bullet
proof”, as required by the most demanding motor
control applications.
