The IC component BQ7693000DBT is a highly integrated battery management system (BMS) designed for multicell lithium-ion battery packs. It provides accurate measurements of cell voltages, pack current, and pack temperature to ensure safe and efficient battery operation.
One of the key features of the BQ7693000DBT is its ability to support up to 15 series-connected cells, making it suitable for a wide range of battery pack configurations. It features an innovative impedance track technology, which allows for highly accurate state-of-charge estimation and cell balancing. This ensures that each cell within the battery pack is properly charged and discharged, maximizing the overall battery capacity and lifespan.
The BQ7693000DBT offers a high level of integration, combining a precision voltage measurement front end, a current measurement circuit, and a dedicated analog-to-digital converter (ADC) for temperature monitoring. This simplifies the design process and reduces the overall component count, resulting in a more cost-effective and space-efficient battery management solution.
To enhance safety, the BQ7693000DBT incorporates comprehensive protection features such as overvoltage protection, undervoltage protection, overcurrent protection, and overtemperature protection. These features help prevent excessive charging/discharging, thermal runaway, and other potential hazards that could lead to battery damage or even catastrophic failure
