PMIC-Battery Management is an important field with a mission to manage electrical power and optimize battery performance. BQ771802DPJR is a new generation of Power Management Integrated Circuit (PMIC) for battery management. It offers a wide range of features and functionalities for a wide range of applications such as batteries for laptops, notebooks, and mobile devices.This PMIC is designed to provide the best performance for battery management and protection. It offers improved performance and superior protection from over-charge and over-discharge, while providing the best possible control over battery charging and discharging. Additionally, the BQ771802DPJR also provides protection against short-circuit, over- temperature, and reverse polarity conditions.The BQ771802DPJR application field and working principle can be broken down into three main components: state of charge, charge monitoring, and cell balance.The state of charge (SoC) determines the current capacity and the energy stored in a battery pack. This is used to identify when the battery has reached the end of its useful life. The BQ771802DPJR is specifically designed to measure the SoC accurately and provide real-time updates. This ensures better control over the battery charging and discharging cycle and helps extend the life of the battery pack.The charge monitoring system monitors the current and voltage of the battery pack at all times. This data is used to evaluate the performance of the battery and provide necessary protection against over-charging, over-discharging, short-circuit, and other possible faults. The BQ771802DPJR also offers a Charge Current Limit feature that can be configured to protect the battery from high current events.The cell balance system is used to maintain the charge difference between cells and prevent over-charging or over-discharging of a single cell. The BQ771802DPJR is specifically designed to monitor the cell voltage and balance the charge between cells. This helps to extend the life of the battery pack by ensuring the cells are always delivering the same amount of charge.The BQ771802DPJR application field and working principle make it an ideal choice for battery management and protection for a range of applications, from laptop and notebook batteries to mobile devices. It offers a comprehensive range of features and functionalities that help to better manage and protect the battery pack and extend its life. With its advanced state of charge monitoring, charge monitoring and cell balance capabilities, the BQ771802DPJR ensures optimal performance and protection.
