TMC5031

POWER DRIVER FOR STEPPER MOTORS INTEGRATED CIRCUITS TMC5031 DATASHEET Dual, cost-effective controller and driver for up to two 2-phase bipolar stepper motors. Integrated motion controller with SPI interface. APPLICATIONS CCTV, Security Antenna Positioning Heliostat Controller Battery powered applications Office Automation ATM, Cash recycler, POS Lab Automation Liquid Handling Medical Printer and Scanner Pumps and Valves FEATURES AND BENEFITS DESCRIPTION The TMC5031 is a low cost motion controller and driver IC for up to two stepper motors. It combines two flexible ramp motion controllers with energy efficient stepper motor drivers. The drivers support two-phase stepper motors and offer an industry-leading feature set, including high-resolution microstepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. All features are controlled by a standard SPI™ interface. 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. 2-phase stepper motors Drive Capability up to 2 x 1.1A coil current Motion Controller with sixPoint™ ramp Voltage Range 4.75… 16V DC SPI Interface 2x Ref.-Switch input per axis Highest Resolution 256 microsteps per full step Full Protection & Diagnostics stallGuard2™ high precision sensorle...
