Battery Management
Products in the Battery Management PMIC (Power Management Integrated Circuit) family are used for battery-related monitoring and control functions including authentication, cell balancing, condition monitoring, fuel gauging, source selection, short circuit protection, over- and under-voltage protection, and others. Note that while some products in this family may include a battery charging function among their features, products implementing a charging function as a principle feature are classified separately.
