Trinamic announces the arrival of a new family of high-performance semiconductor components for stepper motor control. The TMC2208-LA and TMC2224-LA are monolithic components with integrated circuit breakers for up to 1.2A RMS and optimal power controllers for noiseless, sinusoidal control of the motor phases. Above all both components were designed with the goal of easy application in mind.

"Developers are under increasing pressure to shorten development cycles and bring new products on the market faster", explains Michael Randt, founder and CEO of Trinamic. "Our new family of drivers has been specially developed to help making the development process as short and as simple as possible."

Enhanced by the flexible microPlyer interpolater unit, the components offer a resolution of up to 256 microsteps-per-full-step to achieve perfect sinusoidal control, even with low-resolution motion controllers. Further development of Trinamic's stealthChop technololgy, which was introduced two years ago, has all but eliminated motor noise at low speeds, making the precise control of stepper motors not only possible, but affordable for application in environments that demand absolute silence, e.g. office buildings and residential areas.

Due to the immense popularity of stealthChop technology, the components have been designed for compatibility with existing 3D printer electronics. With stealthChop there is no need for costly redesign.

Both components feature a step/direction source for fully autonomous operation. Configuration is achieved via digital inputs.

The TMC2208 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. The device has an integrated microstepping indexer, the completely noiseless current control mode stealthChop2™ and is intended to drive a bipolar stepper motor. The output driver block consists of low RDSon N-Channel power MOSFETs configured as full H-bridges to drive the motor windings. The TMC2208 is capable of driving up to 2A of current from each output (with proper heatsinking). TMC2208 is designed for a supply voltage of 5...36V. The device has a step and direction interface and can be configured with digital pins.
