1 FeaturesThe TMC26x family comprises energy efficient two phase stepper motor drivers with high resolution microstepping capability. They integrate the low resonance chopper spreadCycle for quiet and fast motor operation. The step and direction interface allows simple use and perfectly interfaces the TMC429 motion controller. An SPI™ interface allows for parameterization and diagnostics and can also be used to drive the motor. The TMC262 directly drives four external N/P channel dual MOSFETs for motor currents up to 8A and up to 60V. Protection and diagnostic features further reduce system cost and increase reliability. The TMC260 and TMC261 integrate a power stage for applications up to 40V resp. 60V and 1.7A. Their basic pinning is compatible to the TMC236, allowing a simple upgrade path for existing applications. Its energy efficiency and low power dissipation allow for a miniaturized design with minimum additional infrastructure requirements making it a very cost effective driver.
