DRV8872DDA 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 general guideline is to choose a sense resistor value that results in a voltage drop of around 50-100mV at the maximum motor current.
  • 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 turning it on or off, or to implement a shutdown function.
  • The DRV8872DDA has built-in overcurrent protection, but you can also add external protection components, such as fuses or PTC thermistors, to provide additional protection. Additionally, you can use the sense resistor and the OC (overcurrent) pin to detect overcurrent conditions and take corrective action.
  • The DRV8872DDA can operate up to 100kHz, but the maximum operating frequency depends on the specific application and the motor's characteristics. It's recommended to consult the datasheet and application notes for more information.
