Working Principles
The UCC3913DG4 is designed to protect and monitor battery cells in various applications. It ensures the safe operation of the battery pack by providing overvoltage, undervoltage, overcurrent, and short circuit protection. The IC also incorporates cell balancing functionality to equalize the voltage levels among the cells, which helps extend the overall battery life.
The device continuously monitors the voltage of each cell and compares it to predefined thresholds. If any abnormal condition is detected, such as overvoltage or undervoltage, the IC triggers the appropriate protection mechanism to safeguard the battery cells. Additionally, the UCC3913DG4 can actively balance the cells by diverting excess charge from higher voltage cells to lower voltage cells, ensuring uniform cell performance.
