New Generation of Stepper Motor Drivers Link Optimized Power Control and Simplified Application
Noise levels at low speeds are eliminated with cutting-edge stealthChop™ technology. Hamburg, 07.09.2016 - TRINAMIC Motion Control GmbH & Co. KG, a leading supplier of semiconductors, electronics and mechatronic solutions in the fields of motor and motion control, is proud to announce 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. Trinamic will present the drives to the public at Electronica 2016, in Hall A4 at booth 513.
"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 make 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 components will be available at a price of USD 1.22 at quantities of 1000 as a QFN28 (5x5) package in the first quarter of 2017. To accelerate the design process, Trinamic offers complete end-to-end evaluation kits. The development boards are open-source hardware and freely available for use as a reference design.
The TMC2208-LA is one of the easiest to use monolithic stepper motor drivers. It supports up to 1.2A (RMS). Equipped with stealthChop™ and a resolution of 256 microsteps per fullstep it allows for completely noiseless operation.
The TMC2224-LA is one of the easiest to use monolithic stepper motor drivers. It supports up to 1.2A (RMS). Equipped with stealthChop™ and a resolution of 256 microsteps per fullstep it allows for completely noiseless operation.
