DRV8231ADSGR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 50V, but it's recommended to keep it below 40V 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 implement a shutdown or standby mode in your application.
  • The DRV8231ADSGR has built-in overcurrent protection, but you can also add external protection components, such as fuses or PTC thermistors, to provide additional protection. You can also implement overcurrent detection and shutdown in your application software.
  • The maximum operating frequency of the DRV8231ADSGR is 100kHz, but it's recommended to operate at a frequency below 50kHz for optimal performance and to minimize EMI.
