Solar Energy Harvesting IC with USB output power port and Li-Ion Battery Charger Circuit
The EH01 is a complete power management solution for a variety of energy-harvesting applications, providing a small and simple solution to obtain power from three different sources: a wall adapter, photovoltaic cells and a Li-Ion battery. This device then enables the implementation of USB chargers.
The device contains one high efficiency DC/DC converter, a fully-featured Li-Ion Battery Charger, and numerous protection features.
The EH01 also provides one output for battery status monitoring that gives an estimate of the battery charge level.
