DRV5023AJQLPGMQ1 datasheet by Texas Instruments

DRV5023AJQLPGMQ1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the DRV5023AJQLPGMQ1?
  Texas Instruments provides a recommended PCB layout in the DRV5023 application note (SLVAUH7) which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the desired current sense accuracy and the maximum current that needs to be sensed. A smaller sense resistor value provides better accuracy but increases power loss, while a larger value reduces power loss but decreases accuracy. TI provides a sense resistor calculator tool to help with the selection.
• What is the maximum operating temperature range for the DRV5023AJQLPGMQ1?
  The DRV5023AJQLPGMQ1 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 to prevent overheating and ensure reliable operation.
• Can I use the DRV5023AJQLPGMQ1 in a high-voltage application?
  The DRV5023AJQLPGMQ1 is rated for a maximum voltage of 50V, but it can be used in high-voltage applications with proper external protection circuitry, such as voltage dividers or TVS diodes, to prevent overvoltage damage.
• How do I troubleshoot current sense errors or inaccuracies?
  Common causes of current sense errors include incorrect sense resistor value, poor PCB layout, or noise interference. Troubleshooting steps include verifying the sense resistor value, checking the PCB layout, and using noise filtering techniques, such as adding capacitors or using a low-pass filter.
