APPLICATIONS 3D printers Textile, Sewing Machines Office Automation Consumer, Home CCTV, Security ATM, Cash recycler POS Printers & Scanners DESCRIPTION The TMC2100 is a standalone driver IC. This FEATURES AND BENEFITS small and intelligent standalone driver for two-phase stepper motors offers market- 2-phase stepper motors up to 2.0A coil current (2.5A peak) leading features while being configured by Standalone Driver seven pins only. CPU interaction is not Step/Dir Interface with microstep interpolation required. Drive the motor via Step and MicroPlyer Direction signals. TRINAMICs sophisticated StealthChop chopper ensures noiseless Voltage Range 4.75 46 V DC operation combined with efficiency and Highest Resolution 256 microsteps per full step best motor torque. Integrated power StealthChop for extremely quiet operation and smooth MOSFETs handle motor currents up to 1.2A motion RMS continuously (QFN package) / 1.4A RMS (TQFP) per coil. For saving energy, the SpreadCycle highly dynamic motor control chopper TMC2100 provides standstill current Integrated Current Sense Option reduction. Protection and diagnostic Standstill Current Reduction features support robust and reliable operation. The TMC2100 enables Full Protection & Diagnostics (two outputs) 2 miniaturized designs with low external Small Size 5x6mm QFN36 package or TQFP48 package component count for cost-effective and highly competitive solutions. BLOCK DIAGRAM TRINAMIC Motion Control GmbH & Co. KG Hamburg, Germany TMC2100 DATASHEET (Rev. 1.10 / 2019-NOV-07) 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.
