The TMC2130 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™, the sensorless load dependent current control CoolStep™ and the completely noiseless current control mode StealthChop™ and is intended to drive a bipolar stepper motor. The output driver block consists of low RDSon N-Channel power MOSFETs configured as full H-bridges to drive the motor windings. The TMC2130 is capable of driving up to 2.5A of current from each output (with proper heatsinking). TMC2130 is designed for a supply voltage of 5...46V. The device has a SPI interface for configuration and diagnostics and a step and direction interface.
