TMC262C-LA

TMC262C-LA is a universal, cost-effective stepper driver for two-phase bipolar motors with state-of-the-art features. It offers an industry-leading feature set, including high-resolution micro-stepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication. Integrated protection and diagnostic features support robust and reliable operation. High integration, high energy efficiency and small form factor enable miniaturized designs with a low external component count for cost-effective and highly competitive solutions. Applications include textile, sewing machines, factory automation, lab automation, liquid handling, medical, office automation, printer and scanner, CCTV, security, ATM, cash recycler, POS, pumps and valves, heliostat controllers, and CNC machines.
