该LS0502SCD33是带有备用存储电容器或电容器组的系统的完整解决方案。它集成了输入过压、过流保护电路、反向闭锁开关和超级电容充电控制电路。它还具有内置电池平衡功能，可为双电池超级电容器系统提供保护。当存在主电源并高于最小系统电源电压时，系统将从输入电源获取电力。同时，集成线性充电器以高达 300 mA 的电流为存储元件充电。存储元件充电后，电路仅吸收2.5 μA的电流，同时保持超级电容器或其他存储元件处于就绪状态。当主电源被移除时，集成的反向阻断开关将阻断从系统轨道到输入端的电流。线性充电器将打开，为具有低电阻路径的系统轨供电，电流最高可达 2 A。集成电池平衡电路将在充电时持续监控电池电压，并将两个电池的电压保持在同一水平。该LS0502SCD33可通过外部编程来设定输入电流限制、输入过压、充电电流限制和充电电压限制。当输入电源被拔下时，它会发出一个标志信号，以便主系统可以采取行动。LS0502SCD33采用DFN3X3-10封装。
