TRINAMIC reveals single-axis motion control IC
The device is compatible with a selection of TRINAMIC and third-party motor drive ICs that use an S/D (step/direction) interface. The IC also incorporates an SPI interface to communicate with a host MCU, which issues high-level motion commands that the TMC4210 translates into a series of specific micro-step and direction instructions.
Using a motion control IC that supports multiple axes and complex acceleration profiles exceeds the requirement for many applications, needlessly raising system cost. The single-axis TMC4210 implements a trapezoidal acceleration profile, which is less computationally complex than sinusoidal or S-shaped profiles. This helps reduce device complexity and cost, while delivering performance that satisfies the vast majority of motion control applications.
The TMC4210 is software compatible with TRINAMIC's multi-axes TMC429 motion control IC. It also implements a subset of relevant instructions for single-axis operation and trapezoidal acceleration profiles.
Stepper motors are a cost-effective solution for applications that require high-torque at low speeds and precise control of motor axis rotation. The TMC4210 is sampling in September 2013, and production volumes will be available in December 2013. The device is offered in an SSOP-16 package, priced at Rs.124.55 ($2.08) in 1,000 unit volumes. To support rapid product development and prototyping, TRINAMIC offers a complete TMC4210 design kit with evaluation board.
