BQ771809DPJT Frequently Asked Questions (FAQs)

  • TI recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the IC to improve heat dissipation. A minimum of 1 oz copper thickness is recommended.
  • The BQ771809DPJT is configurable for different battery chemistries through the use of external resistors and capacitors. TI provides a battery configuration tool to help with the design process.
  • The BQ771809DPJT supports charging currents up to 10A, but the maximum current is dependent on the external FETs and PCB design. TI recommends using the device's thermal monitoring feature to prevent overheating.
  • The device has built-in cell balancing functionality. TI recommends using external resistors and capacitors to configure the balancing circuitry. The device's datasheet provides a detailed application circuit for cell balancing.
  • TI recommends using FETs with a minimum current rating of 10A and a maximum RDS(on) of 10mΩ. The FETs should also have a suitable gate-source voltage rating and a low gate charge.
