DRV8838DSGT Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 15V, but 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 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. This pin can be used to implement a shutdown or standby mode in your application.
  • The DRV8838DSGT has built-in overcurrent protection, but it's still important to add external protection measures such as fuses or PTC resistors to prevent damage from excessive currents.
  • The maximum frequency of the input signals that can be applied to the IN1 and IN2 pins is 100 kHz, but it's recommended to keep the frequency below 50 kHz for reliable operation.
