DRV8832QDGQRQ1 datasheet by Texas Instruments

DRV8832QDGQRQ1 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VM pin?
  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.
• How do I choose the correct sense resistor value for my application?
  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 0.1-0.5V at the maximum motor current.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the motor 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 control the motor driver using a microcontroller or other logic circuit.
• How do I protect the DRV8832QDGQRQ1 from overcurrent and overheating?
  You can protect the DRV8832QDGQRQ1 from overcurrent by using a current sense resistor and monitoring the current with an ADC or comparator. For overheating protection, you can use a thermistor or thermal sensor to monitor the driver's temperature and shut it down if it exceeds a certain threshold.
• What is the maximum motor current that the DRV8832QDGQRQ1 can handle?
  The DRV8832QDGQRQ1 can handle a maximum motor current of 2A peak and 1.5A RMS.
