DRV10963PDSNT datasheet by Texas Instruments

DRV10963PDSNT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the DRV10963PDSNT?
  Texas Instruments provides a recommended PCB layout in the DRV10963PDSNT evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize EMI.
• How do I select 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 50-100 mV at the maximum motor current. TI provides a sense resistor calculator tool to help with the selection process.
• What is the maximum operating temperature range for the DRV10963PDSNT?
  The DRV10963PDSNT has an operating temperature range of -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's essential to ensure proper thermal management and heat sinking to prevent overheating and ensure reliable operation.
• Can I use the DRV10963PDSNT with a brushless DC motor?
  No, the DRV10963PDSNT is designed specifically for stepper motor control and is not suitable for brushless DC motor control. TI offers other products, such as the DRV8313, that are designed for brushless DC motor control.
• How do I implement stall detection and protection with the DRV10963PDSNT?
  The DRV10963PDSNT has a built-in stall detection feature that uses the sense resistor voltage to detect motor stalls. TI provides application notes and code examples to help implement stall detection and protection algorithms, including current limiting and fault handling.
