The TMC428 is a miniaturized low cost, but high performance stepper motor controller for up to three motors. It integrates all real time critical tasks in reliable, dedicated hardware: An integrated motion ramp profile generator as well as an adaptable microstep sequencer with microstep RAM table. Advanced stop- and reference switch handling allows for precise and fast referencing as well as on-the-fly position checking. Automatic motor current control gives high motor dynamics while saving energy. The interrupt output can generate precise position pulses.
The TMC428 connects to the TRINAMICs SPI™ drivers (TMC236,TMC239,TMC246 and TMC249) or to Step-/direction drivers. A second SPI™ interface allows communication with a host microcontroller. The host microcontroller just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC428 then automatically calculates the motion ramp based on velocity and acceleration parameters.
The TMC423 adds encoder functionality as well as step- direction impulse forming to the TMC428. Evaluation Boards, application notes, spreadsheets for parameter calculation, C code examples and schematics are available in order to support short design-in times.
