LTC4071 Simple Photovoltaic Charger

Oct 5th 2010
The LTC4071 allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. A near-zero current low battery latching disconnect function protects even the lowest capacity batteries from deep discharge and potentially irreparable damage. The 550nA to 50mA operating current ...

LTC3105/LTC4071 2-Cell Solar Panel Li-Ion Battery Charger

Oct 5th 2010
This circuit shows a compact solar-powered battery charger using a LTC3105 as a boost converter and a LTC4071 as Li-Ion shunt charger. A 2-cell 400mW solar panel provides the input power to the LTC3105 to produce over 60mA of charge current in full sunlight. Maximum power point control prevents the solar panel voltage from dropping ...
