The TMC2202 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. The device has an integrated microstepping indexer, the completely noiseless current control mode StealthChop2™ 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 TMC2202 is capable of driving up to 2A of current from each output (with proper heatsinking). TMC2202 is designed for a supply voltage of 5 to 36V. The device has a step and direction interface and can be configured with digital pins.

TMC2202-WA uses a wettable flank package to allow optical inspection of the soldering joints.
