The TCM5161 Highly compact, powerful cDriver™ from Trinamic

With the TMC5161, Trinamic extends their fully integrated cDriver™ ICs with an integrated motor controller and driver for 2-phase stepper motors up to 3.5A RMS and 8…40V.

Trinamic - TMC5161

After the successful launch of the TMC5160 early 2018, Micromech announces the Trinamic TMC5161. This cDriver™ solution is an easy to use building block with a powerful integrated MOSFET driver stage and complete motion control features, including innovative current regulation

Description:
The TMC5161 is a highly compact stepper motor controller and driver IC. Its power stage is optimized for lowest power dissipation and highest dynamics with Nema 17 and Nema 23 motors. It combines a flexible ramp generator for automatic target positioning with industries’ most advanced stepper motor driver.
Based on TRINAMICs sophisticated spreadCycle and stealthChop choppers, it ensures absolutely noiseless operation combined with maximum efficiency and best motor torque. High integration, high energy efficiency and a small form factor enable miniaturized and scalable systems for cost effective solutions. The complete solution reduces learning curve to a minimum while giving best performance in class. Interface-compatible to TMC5160.

Features and Benefits:

  • 2-phase stepper motors up to 3.5A RMS coil current
  • Step/Dir Interface with 3D optimized interpolation microPlyer™
  • Motion Controller with sixPoint™ramp as intelligent peripheral
  • Voltage Range 8 … 40V DC (55V peak)
  • Low RDSon integrated 45m? MOSFETs
  • SPI & Single Wire UART
  • Encoder Interface and 2x Ref.-Switch Input
  • Highest Resolution 256 microsteps per full step
  • stealthChop2™ for quiet operation and smooth motion
  • Resonance Dampening for mid-range resonances
  • spreadCycle™ highly dynamic motor control chopper
  • dcStep™ load dependent speed control

  • coolStep™ current control for energy savings up to 75%
  • Passive Braking and freewheeling mode
  • Full Protection & Diagnostics
  • Compact Size 10x10mm2 aQFN

Designed with ease of use in mind, the powerful chip can be set up and evaluated easily using Trinamic’s free, easy to use TMCL-IDE software and the modular evaluation kit. This not only minimizes development time, it also allows engineers to quickly try out different parameters for the optimal result, including Trinamic technologies that are in high demand such as SixPoint™ ramping, StealthChop2™, StallGuard2™, and more

Applications:
The cDriver™ is suitable for a wide range of applications from battery powered, high efficiency systems up to embedded applications.

It is ideal for robotics and industrial drives, textile, lab and office automation, medical drives, and next-generation desktop manufacturing applications. The complete solution reduces the learning curve to a minimum while giving the best performance in class.
