DRV10974PWPR Frequently Asked Questions (FAQs)

  • A good PCB layout for the DRV10974PWPR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the device close to the motor. TI provides a recommended PCB layout in the datasheet and application notes.
  • The sense resistor value depends on the motor current and the desired current sense accuracy. A smaller sense resistor value provides higher accuracy but increases the power loss. TI provides a sense resistor calculation formula in the datasheet.
  • The DRV10974PWPR can handle up to 2A of motor current, but the actual current limit depends on the PCB layout, ambient temperature, and other factors. It's essential to follow the thermal design guidelines in the datasheet to ensure reliable operation.
  • The DRV10974PWPR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The device will shut down if the motor current exceeds the programmed threshold.
  • No, the DRV10974PWPR is designed for brushed DC motors only. For brushless DC motor control, you would need a different driver IC, such as the DRV8301 or DRV8323.
