Energy-Efficient Stepper Motor Control With coolStep™ Stepper Driver Family

TRINAMIC's coolStep family are complete microstepping driver ICs with either step-and-direction or SPI operation

Image of Trinamic Motion Control' Energy-Efficient Stepper Motor Control With coolStep™ Stepper Driver FamilyTRINAMIC's coolStep™ families are complete microstepping driver ICs with either step-and-direction or SPI operation. With their high-resolution indexer DAC they allow for resolutions from full-step up to 256 microsteps per full-step, resulting in the smoothest and quietest operation and positioning.

They have an integrated indexer for a perfect sinusoidal-wave-form simple operation without the need of programming microstep tables and where current waveforms are required.

The hysteresis chopper-mode spreadCycle™ reduces resonances and vibrations by automatically selecting the optimum ratio of slow and fast decay for every chopper cycle.

With a full set of diagnostics including open load, short-to-ground, and overcurrent plus the patented sensorless load measurement stallGuard2™ systems with coolStep™ drivers are prepared for highest requirements on reliability and robustness.

Without the need of any sensors, coolStep™ can adapt the motor current according to the load. For evaluation and parameterization for your system evaluation, boards with graphical desktop tools are available.
