DRV8821DCA Frequently Asked Questions (FAQs)

  • The maximum current rating of the DRV8821DCA is 2.5A per phase, but it can be limited by the thermal performance of the PCB and the motor.
  • The microstepping mode can be configured by setting the M0, M1, and M2 pins to select one of 32 microstepping modes. Refer to the datasheet for the specific pin configurations.
  • The TRQ pin is a torque regulation pin that allows the user to adjust the maximum current limit of the motor. A lower voltage on the TRQ pin reduces the maximum current limit, while a higher voltage increases it.
  • Check the enable pin (EN) to ensure it is high, verify the direction (DIR) and step (STEP) pins are being driven correctly, and ensure the motor is properly connected and configured.
  • Yes, the DRV8821DCA can be used with bipolar stepper motors. However, the motor windings must be connected in a unipolar configuration, with each winding connected between a phase output and the sense resistor.
