Trinamic Motion Control

The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors.

Trinamic's sophisticated StealthChop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding StallGuard4 for sensorless homing. The integrated power MOSFETs handle motor currents up to 2A RMS with protection and diagnostic features for robust and reliable operation. A simple to use UART interface opens up tuning and control options. Store application tuning to OTP memory. Industries’ most advanced Step/Dir stepper motor driver family upgrades designs to noiseless and most precise operation for cost-effective and highly competitive solutions.

The TMC2300 low voltage stepper motor driver is intended for battery-operated, space and standby-power critical driver applications. Its silent drive technology StealthChop™ enables non-bugging motion control for portable, home and office applications. A highly efficient power stage, boosted by an internal charge pump for best in-class RDSon resistance, provides high motor current from a tiny package even at low supply voltages. With this, dual AA batteries can be drained down to typically 2.0V (voltage must not drop below 1.8V, provide sufficient supply buffer capacitors).
