It is specially intended for • programmable speed and acceleration de-centralized mechatronic functions. A user-programmable OTP • on-the-fly alteration of target position memory is integrated to store motor parameters and configu- • up to 16 times microstepping ration settings. The TMC211 allows up to four bit of micro • reference switch input read out stepping and is capable of driving a phase current of up to 800 • full protection and diagnostics mA peak. After initialization, it performs all time critical tasks • automatic fast decay and slow decay autonomously based on target positions and velocity param- • low power stand-by mode eters. Together with an inexpensive microcontroller the TMC211 INTERFACE forms a complete motion control system. • field programmable node addresses For using the evaluation board together with the PC software a ELECTRICAL DATA USB-2-X interface is needed. • physical and data link layers conform to LIN rev. 1.2 • up to 800 mA coil current (peak) • supply voltage 8V to 29V PACKAGE • standard SO20 package • RoHS compliant TMC211 Position Controller REF HW address 3 PWM regulator Sequencer LIN Memory 8..29V DC Decoder Temperature protection Control & Diagnostics Step Sinewave table DACs 10 mm internal Driver Stage Motor PWM regulator internal Driver Stage Oscillator OR DE R C O DE D E S C RI P T I ON TMC211-SA Stepper IC with LIN in SO20 package TMC211-EvalBoard Evaluation board for TMC211 Related product: USB-2-X V2 interface converter, TMCM-Motor www.trinamic.com – for detailed information and datasheets 17
