TMCM-1070

The TMCM-1070 from Trinamic is a single axis stepper motor controller/driver module for sensorless load dependent current control. The device is powered by Trinamic spreadCycle™ chopper and stealthChop™ technology. The TMCM-1070 is capable of driving up to 1.4A of current from each output (with proper heatsinking). The device provides a S/D interface and permanent parameter storage via TMCL™-IDE for configuration. TMCM-1070 is an easy to use stepper motor driver module controlled via a step and direction interface. One configuration pin selects the current control mode between stealthChop™ for absolute silent motor control and spreadCycle™ for high speed. A TTL UART interface allows for more advanced configuration, permanent parameter storage via TMCL™-IDE and features microPlyer™ microstep interpolator for obtaining increased smoothness of microstepping over a low frequency STEP/DIR interface.
