BQ7693003DBTR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for accurate measurements. TI recommends a 4-layer PCB with a solid ground plane, and keeping the analog and digital sections separate. Also, keep the sense resistors close to the IC and use a Kelvin connection to minimize errors.
  • Calibration involves adjusting the gain and offset of the ADC to match your battery's characteristics. TI provides a calibration procedure in the datasheet, which involves measuring the battery voltage and current at different SOC points and adjusting the gain and offset accordingly.
  • The BQ76930 can monitor up to 16 series-connected batteries. However, the maximum number of batteries that can be connected depends on the specific application and the desired level of accuracy.
  • The BQ76930 has built-in balancing functionality, which can be enabled through the BAL_CTRL pin. The IC can balance up to 16 cells, and the balancing current can be set through an external resistor.
  • The BQ76930 uses a proprietary SPI-like interface for communication. The interface is similar to SPI, but with some modifications to accommodate the IC's specific requirements.
