TMC261

POWER DRIVER FOR STEPPER MOTORS INTEGRATED CIRCUITS TMC260 & TMC261 DATASHEET Universal, cost-effective stepper drivers for two-phase bipolar motors with state-of-the-art features. Integrated MOSFETs for up to 2 A motor currents per coil. With Step/Dir Interface and SPI. APPLICATIONS 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 Controller CNC Machines FEATURES AND BENEFITS DESCRIPTION The TMC260 and TMC261 drivers for twophase stepper motors offer an industryleading feature set, including highresolution microstepping, sensorless mechanical load measurement, loadadaptive power optimization, and lowresonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication. Integrated power MOSFETs handle motor currents up to 2A per coil. 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. Drive Capability up to 2A motor current Highest Voltage up to 60V DC (TMC261) or 40V DC (TMC260) Highest Resolution up to 256 microsteps per full step Compact Size 10x10mm QFP-44 package Low Power rectification Dissipation, low RDSON & synchronous EMI-optimized programmable slope Protection & Diagnostics overcurrent, overtemp...
