DRV8871DDA 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.
  • The EN pin is an active-high enable input that allows the device to be enabled or disabled. When EN is high, the device is enabled, and when EN is low, the device is disabled and all outputs are turned off.
  • The DRV8871DDA can be configured for half-bridge or three-phase operation by connecting the appropriate pins and configuring the input signals. Refer to the datasheet and application notes for specific configuration details.
  • The DRV8871DDA can handle switching frequencies up to 100 kHz, but the maximum frequency depends on the specific application and motor characteristics.
