BQ25708RSNR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • Use the TI WEBENCH Power Designer tool to generate a compensation network design based on the specific application requirements. The tool provides a recommended compensation network component values and layout guidelines.
  • The BQ25708RSNR can handle input voltages up to 22V, but it's recommended to keep the input voltage below 18V to ensure reliable operation and minimize the risk of overvoltage stress.
  • Monitor the input voltage, output current, and junction temperature to ensure they are within the recommended operating ranges. Use thermal design and layout techniques to keep the junction temperature below 125°C.
  • Yes, the BQ25708RSNR is rated for operation up to 105°C, but the maximum junction temperature should not exceed 125°C. Use thermal design and layout techniques to keep the junction temperature below 125°C.
