凌力尔特的许多电池管理产品都把我们的独立型电池充电器功能与一种或多种其他功能結合。例如：凌力尔特的 PowerPath 产品和架构允许从 VIN 和电池向负载供电，从而确保了较短的充电时间，并使便携式设备设计师获得了更大的灵活性。它们还可在电池耗尽的情况下于系统中实现“即时接通”。与我们的电池充电器组合在一起的其他功能包括：用于 USB 和墙上适配器的双路输入、开关稳压器、比较器或 LDO。
PMIC (DC-DC、PowerPath 和电池充电器)：电源管理集成电路 (PMIC) 用于在便携式产品中完成电池充电操作并提供多个系统电源轨。PowerPath 控制在多种输入电源 (例如：墙上适配器、USB 端口和锂离子电池) 之间实现了无缝切换，并负责管理这些输入电源之间的功率流动，同时优先向系统负载供电。高效率的开关模式电源管理能够从墙上适配器和基于 USB 的电源提供较高的充电电流。
