MAS6011 – Solar Cell Energy Harvesting System Manager

Targeted for solar powered wireless modules

Helsinki, Finland – 02 November 2011 

Micro Analog Systems Oy today announced the MAS6011 Solar Cell Energy Harvesting System Manager.

MAS6011 monitors the supply voltage and charging of a battery-powered system containing a small solar cell. The current consumption of this IC is extremely low, 110 nA, which means the system can charge from very low light conditions and also stay in MAS6011 press photopower down mode for years and still operate directly from the battery before recharging.

To be able to charge a battery also in conditions with very limited light, a large solar cell is usually used. This can on the other hand easily destroy the battery due to over voltage during strong sun light. MAS6011 solves this dilemma and will give secure protection of a secondary 3V battery over a big range of light strengths (lx).

The switching levels have been designed for usage with rechargeable 3V Lithium Vanadium (VL-type) batteries. Those batteries are compact, button-shaped, secondary batteries with very high energy compared to more traditional batteries. The self discharge rate is less than 2% a year which makes them very useful as a power source in systems that might be stored for a long time without re-charging.

Possible applications for MAS6011 include Wireless Sensor Modules, GPS Modules, Electronic locks, Watches, Energy Harvesting etc.
