Low-Cost Stand-Alone Stepper Motor Driver with Step/Direction (1,4A/36V)
The TMC2208 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 TMC2208 is capable of driving up to 2A of current from each output (with proper heatsinking). TMC2208 is designed for a supply voltage of 5...36V. The device has a step and direction interface and can be configured with digital pins.
Pin compatible with Allegro A4988
