The TMC2590 is a high-performance power driver for two-phase bipolar stepper motors. It is designed to drive four external N- and P-channel dual MOSFETs, supporting motor currents up to 8A and operating voltages up to 60V DC. It features stallGuard2 for sensorless load detection, coolStep for energy-efficient current control, and spreadCycle for high-precision chopper operation. The device is controlled via SPI and STEP/DIR interfaces and includes comprehensive protection and diagnostic features such as short-circuit, overtemperature, and undervoltage protection.
