The TMC2660 is a single-axis, energy-efficient stepper motor driver with integrated power MOSFETs. It achieves a low power dissipation for a 4A stepper motor driver with an RDS(on) of 65mΩ, eliminating the need for a heat sink. It features stallGuard2, coolStep, and spreadCycle technologies for high-precision control and sensorless load detection.
