BQ25895MRTWT 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 connect the IC to the ground plane.
  • Use the bqStudio software to customize the charging profile based on the battery's chemistry, capacity, and recommended charging parameters. Consult the battery manufacturer's datasheet for specific guidelines.
  • The IC has a thermal shutdown feature that activates at 150°C. Ensure good airflow, use a heat sink if necessary, and follow the recommended PCB layout to minimize thermal resistance. Monitor the IC's temperature using the THERM pin.
  • Use external resistors and zener diodes to implement OVP and UVP. The BQ25895MRTWT has a built-in comparator for OVP, and an external circuit can be used for UVP. Consult the datasheet for specific implementation details.
  • Follow the recommended PCB layout and component placement to minimize EMI. Use shielding, filtering, and grounding techniques to reduce emissions. Ensure compliance with regulatory standards such as CISPR 22 and FCC Part 15.
