TRINAMIC Offers World’s Lowest Cost Single-Axis Motion Controller IC
New Device Minimizes Lifetime Cost of Ownership for Cost-Sensitive Designs
TRINAMIC Motion Control announced the world’s lowest cost single-axis motion controller IC. The new TMC4210 motion controller performs all real-time position and velocity stepper motor calculations, relieving a host microcontroller from the software design complexity required to implement a motor control system.
TRINAMIC Motion Control 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 65 milliohm, 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.
