Dual-Axis Stepper Motor Controller and Driver IC with stealthChop™

TRINAMIC's dual-axis stepper integrated controller driver IC family are powerful systems-on-a-chip, integrating sophisticated ramp-generators and two power stages, plus best-in-class diagnostics and protection in a tiny 7 mm by 7 mm QFN package.

With the newest members of this family, TMC5041 and TMC5072, TRINAMIC also adds the new stealthChop technology, minimizing low speed hum of stepper motors by implementing a PWM algorithm that relies predominantly on voltage modulation for motor control at lower speeds. This technology minimizes PWM current fluctuation.

Noise limitations are especially desirable in applications that normally occur in close proximity to human operators, in applications where multiple stepper motors are in use, in video surveillance applications where installations near walls and ceilings amplify noise, and in consumer applications, like home automation and air conditioning, where users expect minimal noise.
