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)
