BQ78350DBT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure that the thermal pad is connected to a large copper area to dissipate heat efficiently.
  • Use the bq78350DBT's programmable charging profile feature to customize the charging curve for your specific battery chemistry. Consult the datasheet and application notes for guidance on setting the charging parameters.
  • The maximum charging current is 3A, but it's recommended to limit it to 2A for optimal performance and thermal management. Higher currents may require additional thermal design considerations.
  • Yes, the bq78350DBT supports charging multiple batteries in parallel. However, ensure that the total charging current does not exceed the IC's maximum rating, and that the batteries are properly balanced and monitored.
  • The bq78350DBT has built-in overcharge protection. Set the OVP (Over-Voltage Protection) threshold using the OVP pin, and the IC will automatically terminate charging when the battery voltage reaches the set point.
