Stepper motor driver 5 to 40V, up to 1.4A with S/D and SPI Interface, 256 µSteps, CoolStep, StallGuard2 and SpreadCycle

The TMC260 provides an integrated motor driver solution for Laboratory Automation, 3D-Printing, Scanners and other automated equipment applications. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™ and the sensorless load dependent current control CoolStep™ and is intended to drive a bipolar stepper motor. The output driver block consists of low RDSon TrenchFET power MOSFETs configured as full H-bridges to drive the motor windings. The TMC260 is capable of driving up to 2A of current from each output (with proper heatsinking). TMC260 is designed for a supply voltage of 9 to 40V. The device has a SPI interface for configuration and diagnostics and a step and direction interface.
