Motor Driver ICs

xSPINTM Motor drivers: integration, performance, efficiency, leading in motion control

Designing motor control applications becomes much easier with the outstanding performance, features and support of ST’s complete portfolio of motor drivers.
Featuring motion control with up to 1/128 microsteps resolution and digital motion profiles with acceleration, deceleration, speed or target position easily user-selectable via SPI, ST’s stepper motor drivers provide a level of smoothness of profile precision never experienced before.
System-in-package solutions integrating the high performing control core and discrete MOSFETs enable an unprecedented level of current density up to 10Arms.
These products are scalable, reliable and cost effective. They are designed with an extensive diagnostics capability, and are also fully protected.
Multi-package options address a variety of design challenges such as space and thermal constraints.

powerSTEP: 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 speed profile generation and positioning calculations.

cSPIN: SPI advanced controller for stepper applications up to 85 V, providing fully digital control of the motion through speed profile generation and positioning calculations.
It integrates a dual full bridge gate driver for external MOSFETs with embedded non-dissipative overcurrent protection.

dSPIN: New state-of-the-art platform for stepper motor drives, a quantum leap in micro-stepping. Substitutes expensive DSP, analog and power components with a single IC. Its fully-digital motion engine with SPI interface controls the stepper motor with up to 128 microsteps, and the innovative voltage-mode technique allows for unprecedented motion smoothness.

FlexSPIN: Highly integrated for cost-driven applications such as printers. Controls and drives multi-motor applications (stepper and DC simultaneously) or inverter stages with its 4 fully-configurable full-bridge drivers.

easySPIN: Best trade-off between performance and cost for microstepping applications. No external shunts required due to an innovative current-mode scheme.

powerSPIN: Integrated PWM controller and DMOS bridge for brush DC, bipolar stepper and permanent-magnet 3-phase brushless motors, offering non-dissipative overcurrent detection.
