POWER DRIVER FOR STEPPER MOTORS INTEGRATED CIRCUITS TMC2100-LA DATASHEET Standalone intelligent Step/Direction driver for two-phase bipolar stepper motor. stealthChop for quiet movement. Integrated MOSFETs for up to 2.0 A motor current per coil. APPLICATIONS Textile, Sewing Machines Office Automation Consumer, Home CCTV, Security ATM, Cash recycler POS Printers & Scanners DESCRIPTION The TMC2100 is TRINAMICs most FEATURES AND BENEFITS autonomous driver IC. This small and intelligent standalone driver for two phase 2-phase stepper motors up to 2.0A coil current (2.5A peak) stepper motors offers market-leading Standalone Driver features while being configured by seven Step/Dir Interface with microstep interpolation pins only. CPU interaction is not required. mi cr oPl ye r Drive the motor via Step and Direction signals. TRINAMICs sophisticated Voltage Range 4.75 46 V DC stealthChop chopper ensures noiseless Highest Resolution 256 microsteps per full step operation combined with efficiency and ste alt h Ch op for extremely quiet operation and smooth best motor torque. Integrated power motion MOSFETs handle motor currents up to 1.2A RMS continuously (QFN package) / 1.4A RMS sp r e ad Cy cle highly dynamic motor control chopper (TQFP) per coil. For saving energy, the Integrated Current Sense Option TMC2100 provides standstill current Standstill Current Reduction reduction. Protection and diagnostic features support robust and reliable Full Protection & Diagnostics (two outputs) 2 operation. The TMC2100 enables Small Size 5x6mm QFN36 package or TQFP48 package miniaturized designs with low external component count for cost-effective and highly competitive solutions.

KG Hamburg, Germany TMC2100 DATASHEET (Rev. 1.07 / 2017-MAY-15) 2 APPLICATION EXAMPLES: SIMPLE SOLUTIONS HIGHLY EFFECTIVE The TMC2100 scores with power density, integrated power MOSFETs, smooth and quiet operation, and a congenial simplicity. The TMC2100 covers a wide spectrum of applications from battery systems up to embedded applications with up to 2.0A motor current per coil. TRINAMICs unique chopper modes spreadCycle and stealthChop optimize drive performance. stealthChop reduces motor noise to the point of silence during low velocities. Standby current reduction keeps costs for power dissipation and cooling down. Extensive support enables rapid design cycles and fast time-to-market with competitive products. STANDALONE DESIGN FOR ONE STEPPER MOTOR In this example, configuration is hard wired. The motor is driven via step 0A+ S/D and direction signals. Motion control N S TMC2100 0A- tasks and interpreting ERROR and ERROR, INDEX INDEX are software based. 0B+ 0B- . Here, the CPU sends step and direction MINIATURIZED DESIGN FOR ONE STEPPER MOTOR signals to the TMC2100 and reads out 0A+ ERROR and INDEX for diagnostic tasks. S/D N High-Level Further, the CPU configures the S CPU ERROR, INDEX TMC2100 0A- Interface TMC2100 and manages motion control. 0B+ Based on Step/Dir signals, the TMC2100 0B- Configuration / Enable provides motor currents for each axis and smoothens and optimizes drive performance. EVALUATION BOARD SYSTEM The TMC2100-EVAL is part of TRINAMICs universal evaluation board system which provides a convenient handling of the hardware as well as a user-friendly software tool for evaluation. The TMC2100 evaluation board system consists of three parts: STARTRAMPE (base board), ESELSBRCKE (connector board with several test points), and TMC2100-EVAL.
