STMICROELECTRONICS POWERSTEP01 Motor Controller, MOSFET, Stepper, SPI Interface, 7.5 V to 85 V Supply, 10 A Out, VFQFPN-89

POWERSTEP01 is a system-in-package integrating 8 N-channel 16mohm MOSFET for stepper applications up to 85V 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 analogue values (i.e. current protection trip point, dead time, PWM frequency, etc.) are sent through a standard 5Mbit/s SPI.
