DRV8839DSSR 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. However, it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I configure the device for a specific motor type?
  The DRV8839DSSR is a general-purpose motor driver and can be configured for different motor types by adjusting the external components and the input logic levels. Refer to the application notes and the datasheet for specific configuration examples.
• What is the maximum current that the device can handle?
  The DRV8839DSSR can handle a maximum current of 2A per channel. However, the actual current handling capability depends on the PCB design, thermal management, and the motor's current requirements.
• How do I protect the device from back-EMF and voltage spikes?
  Use external diodes or TVS diodes to protect the device from back-EMF and voltage spikes. Additionally, ensure that the device is properly decoupled and that the PCB is designed to minimize electromagnetic interference (EMI).
• Can I use the DRV8839DSSR for brushless DC (BLDC) motor control?
  No, the DRV8839DSSR is designed for brushed DC motor control. For BLDC motor control, consider using a dedicated BLDC motor driver IC, such as the DRV8301 or DRV8305.
