BQ24308DSGT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use thermal vias to dissipate heat.
  • Use a low-impedance current sense resistor (e.g., 1 mΩ) and place it close to the device. Ensure the sense lines are short and shielded to minimize noise and interference.
  • The BQ24308DSGT is rated for operation up to 105°C ambient temperature. However, for reliable operation, it's recommended to keep the ambient temperature below 85°C to ensure optimal performance and longevity.
  • Yes, but ensure the device is properly secured to the PCB using a suitable mounting method (e.g., screw or adhesive). Additionally, consider using a vibration-dampening material or potting the device to minimize the effects of vibration.
  • Use a logic analyzer or oscilloscope to monitor the device's signals (e.g., EN, FLT, and SENSE). Check the datasheet for specific troubleshooting guidelines and consult the TI support resources for additional assistance.
