DRV8833CRTET 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 around 50-100mV at the maximum motor current.
• What is the purpose of the nSLEEP pin, and how do I use it?
  The nSLEEP pin is an active-low input that puts the device into a low-power sleep mode when driven low. This can be used to reduce power consumption when the motor is not in use. To use it, simply drive the nSLEEP pin low to enter sleep mode, and drive it high to exit sleep mode.
• How do I configure the device for half-bridge or full-bridge operation?
  The DRV8833CRTET can be configured for half-bridge or full-bridge operation by connecting the appropriate pins. For half-bridge operation, connect the OUT1 and OUT2 pins together, and for full-bridge operation, connect the OUT1 and OUT2 pins to separate motor windings.
• What is the maximum current that the device can handle?
  The DRV8833CRTET can handle a maximum current of 2A per channel, but this can be limited by the PCB design, thermal considerations, and other factors. Be sure to check the thermal and current handling capabilities of your specific design.
