1 Features
The TMC222 is a combined micro-stepping stepper motor motion controller and driver with RAM and
OTP memory. The RAM or OTP memory is used to store motor parameters and configuration settings.
The TMC222 allows up to four bit of micro stepping and a coil current of up to 800 mA. After
initialization it performs all time critical tasks autonomously based on target positions and velocity
parameters. Communications to a host takes place via a two wire serial interface. Together with an
inexpensive micro controller the TMC222 forms a complete motion control system. The main benefits
of the TMC222 are:
• Motor driver
• Controls one stepper motor with four bit micro stepping
• Programmable Coil current up to 800 mA
• Supply voltage range operating range 8V ... 29V
• Fixed frequency PWM current control with automatic selection of fast and slow decay mode
• Full step frequencies up to 1 kHz
• High temperature, open circuit, short, over-current and under-voltage diagnostics
• Motion controller
• Internal 16-bit wide position counter
• Configurable speed and acceleration settings
• Build-in ramp generator for autonomous positioning and speed control
• On-the-fly alteration of target position
• reference switch input available for read out
• Two wire serial interface
• Transfer rates up to 350 kbps
• Diagnostics and status information as well as motion parameters accessible
• Field-programmable node addresses (32)
