The TMC2590 driver for two-phase stepper motors offers an industry-leading feature set, including high-resolution microstepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. It uses external N- and P-channel MOSFETs for motor currents from 1A up to roughly 8A. The TMC2590 offers standard SPI and Step/Dir interfaces to simplify communication as well as stand alone configuration options.
