The TMC262C drivers for two-phase stepper motors offer an industry-leading feature set, including high-resolution microstepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication. The TMC262 uses four external N- and P-channel dual-MOSFETs for motor currents up to 10A RMS and up to 60V. Integrated protection and diagnostic features support robust and reliable operation. High integration, high energy efficiency and small form factor enable miniaturized designs with low external component count for cost-effective and highly competitive solutions. The new –C device improves motor silence and adds low side short protection.
