TRINAMIC Expands Stepper Motor Driver Line with
New 4A Device
Integrating Pre-Driver and MOSFET Amplifiers, New IC Offers Lowest Power Dissipation for 4A Stepper
Hamburg, Germany (15 July 2013)—TRINAMIC Motion Control, a leading global developer of motor and motion
control technologies, expanded the company’s existing product line of micro-stepping motor drives with a new
IC that supports motor drive currents up to 4A. The new TMC2660 integrates both a pre-driver for real-time
calculation of motor coil current values, and power MOSFETS for amplification of coil outputs to directly drive
an external motor.
Packaged in a single multi-chip module, the integrated driver/amplifier achieves the lowest power dissipation
currently available for a 4A stepper motor driver. With an Rds(on) of 65mΩ, the TMC2660 dissipates just 2.8W at
4A, an 85% reduction compared with the most competitive solution previously available. The new device’s
minimal power dissipation eliminates the need for a heat sink, enabling highly dense board designs and
reduced component count and cost.
“Our popular TMC260 and TMC261 Stepper Motor Drivers have been widely adopted by manufacturers
worldwide,” explained TRINAMIC Founder and CEO Michael Randt. “Our customer base requested that we
expand our line to support higher current levels, and we responded by introducing the TMC2660.”
With a peak output current rating of 4A, the TMC2660 can drive motors as large as NEMA 23. The new device is
both pin- and software-compatible with TRINAMIC’s popular TMC260/261 devices, which support motors up to
NEMA 17.
Stepper motors are a cost-effective solution for applications that require high-torque at low speeds and precise
control of motor axis rotation. Widely used in printers, scanners, robotics, medical and scientific equipment and
other applications, TRINAMIC estimates that more than one billion stepper motors are shipped ever year.
The TMC2660 is sampling in August 2013, and production volumes will be offered in Q4 2013. The device is
available in a 44-pin PQFP package.
To support rapid product development and prototyping, TRINAMIC offers a complete TMC2660 design kit with
evaluation board, as well as an Arduino daughter card (shield).
Based in Hamburg, Germany, privately-held TRINAMIC Motion Control GmbH & Co. KG is a recognized global
leader in motor and motion control technologies. Leveraging its extensive portfolio of internally developed IP,
TRINAMIC motor control products emphasize efficiency, quality and ease-of-use.
The company sells ICs, modules and integrated mechatronics to market leading manufacturers worldwide. The
company’s products have been integrated into a wide range of applications in biotechnology, lab automation,
materials handling, CCTV and factory automation. More information about TRINAMIC can be obtained on the
