TMC2226-SA-T Frequently Asked Questions (FAQs)

  • A good PCB layout for optimal thermal performance involves placing the TMC2226-SA-T near the edge of the board, using a large copper area for heat dissipation, and minimizing the number of layers under the device. Additionally, using thermal vias and a thermal pad can help to dissipate heat more efficiently.
  • To configure the TMC2226-SA-T for silent operation, you can use the StealthChop feature, which reduces the noise level of the motor by spreading the current spectrum. This can be done by setting the CHOPCONF register to the StealthChop mode and adjusting the chopping frequency and amplitude to optimize for silent operation.
  • The TMC2226-SA-T can handle a maximum motor current of 2.8A peak and 1.4A RMS. However, the actual current handling capability may be limited by the PCB layout, thermal design, and other system-level factors.
  • The TMC2226-SA-T has a built-in stall detection feature that can be enabled by setting the STALLCONF register. The device can detect stalls based on the motor current and velocity. When a stall is detected, the device can be configured to reduce the motor current or shut down the motor to prevent damage.
  • The recommended power supply decoupling for the TMC2226-SA-T involves using a combination of ceramic and electrolytic capacitors to filter out noise and ripple on the power supply lines. A minimum of 10uF ceramic capacitor and 100uF electrolytic capacitor are recommended, with the capacitors placed as close as possible to the device.
