The BQ7692000PWR is an integrated circuit (IC) component designed for battery management systems (BMS). It offers a wide range of features to accurately monitor and control battery packs, ensuring their safety and efficiency.
One of the key features of the BQ7692000PWR is its ability to measure individual cell voltages in a battery pack. It has an onboard voltage measurement unit that can handle up to 15 series-connected lithium-ion or lithium-polymer cells, making it suitable for various battery pack configurations. The IC provides precise voltage readings with a resolution of up to 0.625 mV per cell.
Additionally, the BQ7692000PWR incorporates an internal temperature sensor, enabling it to monitor battery pack temperature. This feature is critical for preventing overheating and ensuring the battery operates within safe temperature limits. The IC constantly measures the temperature and provides accurate readings to the BMS.
Furthermore, the BQ7692000PWR includes built-in protection features to safeguard the battery pack. It has overvoltage protection, undervoltage protection, and overcurrent protection capabilities. These protections ensure that the battery cells are not charged beyond their maximum limits, discharged to dangerously low voltages, or subjected to excessive currents that could damage them.
The IC also offers communication capabilities through a serial interface, enabling it to interface with a microcontroller or host device
