Integrated Circuits Motion Controllers for Stepper Motors TMC 453 High End Motion Controller with Encoder Interface for Stepper Motors The TMC453 is a high-end motor controller for all common 2-, 3-, and 5-phase stepper motors. It provides encoder feedback for high reliability or high position resolution drives. A large set of motion control features is included on this IC. The various function blocks are hardwired and „ready-to-use“. All processes can be serialized using the instruction based interface. A complete linear & S-shaped ramp generation unit is integrated within the TMC453. All dynamic parameters can be adjusted for a given application in a very broad range. The CPU is relieved from all time critical tasks like ramp calculation or microstep generation. Thus CPU and software engineer can focus on higher level motion control jobs. In many applications, the TMC453 reduces the time time-to-market, and it saves costs for software development and hardware engineering. The TMC453 turns stepper motors into easy to use peripherals! A PC based evaluation kit is available that comes together with software for demonstration of all TMC453 capabilities.
