FEATURES AND BENEFITS 2-phase stepper motors up to 2A coil current (peak) STEP/DIR Interface with 2, 4, 8, 16 or 32 microstep pin
setting Smooth Running 256 microsteps by microPlyer™ interpolation stealthChop2™ silent motor operation spreadCycle™ highly dynamic motor control chopper Low RDSon LS 280mΩ & HS 290mΩ (typ. at 25°C) Voltage Range 4.75… 36V DC Automatic Standby current reduction (option) Internal Sense Resistor option (no sense resistors required) Passive Braking and Freewheeling Single Wire UART & OTP for advanced configuration options Integrated Pulse Generator for standalone motion Full Protection & Diagnostics Choice of QFN, TQFP and HTSSOP packages for best fit
APPLICATIONS Compatible Design Upgrade 3D Printers Printers, POS Office and home automation Textile, Sewing Machines CCTV, Security ATM, Cash recycler HVAC
DESCRIPTION The TMC2202, TMC2208, TMC2220, TMC2224
and TMC2225 are ultra-silent motor driver
ICs for two phase stepper motors. Their
pinning is compatible to a number of
legacy drivers. TRINAMICs sophisticated
stealthChop2 chopper ensures noiseless
operation, maximum efficiency and best
motor torque. Its fast current regulation
and optional combination with spreadCycle
allow for highly dynamic motion.
Integrated power-MOSFETs handle motor
current up to 1.4A RMS. Protection and
diagnostic features support robust and
reliable operation. A simple to use UART
interface opens up more tuning and
control options. Application specific tuning
can be stored to OTP memory. Industries’
most advanced STEP/DIR stepper motor
driver family upgrades designs to noiseless
and most precise operation for costeffective and highly competitive solutions. TMC2202, TMC2208, TMC2220, TMC2224, TMC2225 Step/Dir Drivers for Two-Phase Bipolar Stepper Motors
up to 2A peak - stealthChop™ for Quiet Movement - UART Interface Option.
