本文提出了一款超低静态电流（330nA）的能量采集充电与电池管理IC，能够从太阳能板和热电发电机高效提取能量并为电池或超级电容充电。该芯片集成了完整的电池管理功能，解决了以往能量采集DC-DC转换器缺乏电池管理的问题。
Harvesting energy from ambient energy sources such as solar and thermal gradients is one solution to address the dramatic increase in energy consumption of personal electronics. In this paper, an ultra low quiescent current charger and battery management IC that can efficiently extract energy from solar panels and thermoelectric generators to charge batteries and super capacitors is presented. While previous works on energy harvesting [1-5] report efficient DC-DC converters to extract the energy from the harvester, not all of them provide complete battery management functionality for various chemistries. Also, maximum power point tracking (MPPT) which is critical in energy harvesting applications is not provided in some of the published work. In this paper, a charger and battery management IC with 330nA quiescent current i
