DRV8873SPWPRQ1 Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 36V for reliable operation.
  • The sense resistor value depends on the motor current and the desired current sense accuracy. A good starting point is to use the formula Rsense = 0.05 / Imax, where Imax is the maximum motor current. Then, adjust the value based on the desired current sense accuracy and the motor's characteristics.
  • The EN (enable) pin is used to enable or disable the driver. When EN is high, the driver is enabled, and when EN is low, the driver is disabled. You can use the EN pin to control the motor's operation, such as to implement a shutdown function or to reduce power consumption when the motor is not in use.
  • The DRV8873 has a built-in overcurrent protection (OCP) feature that limits the motor current to a safe value. You can also add external protection components, such as fuses or PTC thermistors, to provide additional protection. Additionally, you can use the current sense output (ISENSE) to monitor the motor current and implement your own overcurrent protection scheme.
  • The maximum operating frequency of the DRV8873 is 100 kHz. However, the actual operating frequency may be limited by the motor's characteristics and the application's requirements.
