DRV8837DSGT Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 15V. However, it's recommended to keep it below 12V 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. Adjust the value based on your specific application requirements.
  • The EN (enable) pin is used to enable or disable the motor driver. When EN is high, the driver is enabled, and when it's low, the driver is disabled. You can use this pin to control the motor driver using a microcontroller or other logic circuit.
  • To protect the DRV8837 from back-EMF, you can add a freewheeling diode (e.g., 1N4001-1N4007) in parallel with the motor. This diode allows the back-EMF to safely dissipate, preventing damage to the driver.
  • The DRV8837 can handle a maximum motor current of 1.5A per channel. However, the actual current handling capability depends on the PCB layout, thermal management, and ambient temperature.
