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)

2.2 Position Controller / Main Control
Motor parameters, e.g. acceleration, velocity and position parameters are passed to the main control
block via the serial interface. These information are stored internally in RAM or OTP memory and are
accessible by the position controller. This block takes over all time critical tasks to drive a stepper
motor to the desired position under abiding the desired motion parameters.
The main controller gets feedback from the stepper motor driver block and is able to arrange internal
actions in case of possible problems. Diagnostics information about problems and errors are
transferred to the serial interface block.
2.3 Stepper Motor Driver
Two H-bridges are employed to drive both windings of a bipolar stepper motor. The internal transistors
can reach an output current of up to 800 mA. The PWM principle is used to force the given current
through the coils. The regulation loop performs a comparison between the sensed output current and
the internal reference. The PWM signals to drive the power transistors are derived from the output of
the current comparator.
2.4 Two Wire Serial Interface
Communication between a host and the TMC222 takes places via the two wire bi-directional serial
interface. Motion instructions and diagnostics information are provided to or from the Main Control
block. It is possible to connect up to 32 devices on the same bus. Slave addresses are programmable
via OTP memory or an external pin.

5.1.5 Vmin Parameter
The minimum velocity parameter is a programmable ratio between 1/32 and 15/32 of Vmax. It is also
possible to set Vmin to the same velocity as Vmax by setting Vmin index to zero. The table below
shows the possible rounded values of Vmin given within unit [FS/s].
