DRV8828PWPR datasheet by Texas Instruments

DRV8828PWPR Frequently Asked Questions (FAQs)

• What is the maximum current rating of the DRV8828PWPR?
  The maximum current rating of the DRV8828PWPR is 2.5A per phase, with a peak current of 3A per phase.
• How do I configure the microstepping mode on the DRV8828PWPR?
  The microstepping mode can be configured using the M0, M1, and M2 pins. The M0 pin selects between full-step and microstepping modes, while the M1 and M2 pins select the microstepping resolution (e.g., 1/2, 1/4, 1/8, etc.).
• What is the purpose of the TRQ pin on the DRV8828PWPR?
  The TRQ (Torque Regulation) pin is used to adjust the current limit of the motor. By connecting a resistor between the TRQ pin and GND, the current limit can be set to a specific value.
• How do I handle thermal shutdown on the DRV8828PWPR?
  The DRV8828PWPR has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 170°C. To handle thermal shutdown, ensure proper heat sinking and thermal design, and consider using a thermal monitor or shutdown circuit to detect and respond to thermal events.
• Can I use the DRV8828PWPR with a bipolar stepper motor?
  Yes, the DRV8828PWPR can be used with bipolar stepper motors. The device supports both unipolar and bipolar stepper motor configurations.
