BQ7693001DBT Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. The layout should also minimize noise and interference by keeping the sense lines short and away from high-current paths.
  • Calibration is done through the I2C interface using the CAL_VSENSE and CAL_ISENSE registers. The device should be in a known state (e.g., with a known voltage and current) during calibration. TI provides a calibration procedure in the datasheet and application notes.
  • The BQ76930x can monitor up to 16 series-connected cells. However, the device can be cascaded to monitor more cells, but this requires additional external circuitry and complexity.
  • The BQ76930x has built-in cell balancing capabilities with three modes: passive balancing, active balancing, and hybrid balancing. The device can also be configured to use external balancing FETs or resistors.
  • The BQ76930x supports I2C, SPI, and UART communication protocols. The protocol is selected through the COMM_MODE register, and the device can be configured using the TI-provided software development kit (SDK) or by writing custom code.
