Lin Engineering Intros TMC222 Motor Controller/Driver

November 08, 2005 by Jeff Shepard

Lin Engineering Inc. (Santa Clara, CA), a designer of step motors, introduced its new TMC222 micro-stepping stepper motor controller and driver with LIN interface and RAM and OTP memory, which is used to store motor parameters and configuration settings. The TMC222 allows up to four bits of micro-stepping, and a coil current of up to 800 mA. After initialization, the TMC222 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 microcontroller, the TMC222 forms a complete motion control system.
