How To Use TMC2130 Motor Driver IC?

The TMC2130 is a 2-phase stepper motor driver that is capable of supplying up to 2A. It can communicate with an external microcontroller through an SPI and STEP/DIR interface.

It also integrates proprietary functions such as:

• stealthChop: a smoothing algorithm that makes movement and standstill inaudible
• spreadCycle: an algorithm for high dynamic motion and clean current waveform
• dcStep: load dependent speed control
• stallGuard2: sensorless stall detection and load measurement
• coolStep: load-dependent current consumption for high efficiency
• microPlyer: microstep interpolation to achieve smooth movement when using the STEP/DIR interface

The TMC2130 has three modes of operation:

1. STEP/DIR Driver Mode

An external microcontroller generates STEP and DIRECTION signals.

The STEP input is in the form of pulses that controls motor movement, and the DIR signal indicates the movement direction.

2. Standalone Mode

No external microcontroller is required and the movement is done using the STEP and DIR inputs. Configuration is done through the hardware pins.

3. SPI Driver Mode

Operation in this mode is combined with the TMC4361 IC to provide full control over the motor current.

 

Applications 

• Factory and lab automation
