Product Description

The TMC62C 20A combines both a motion controller and a driver. It is designed to efficiently manage stepper motors using Trinamic's proprietary technology for advanced current control, motion profiling, and microstepping. The IC integrates several advanced features to improve motor performance, reduce power consumption, and provide precise motion control with high torque and low vibration. It can be used for driving both unipolar and bipolar stepper motors.
