DESCRIPTION

The MAS6011 solar cell system manager 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 power down

mode for years and still operate directly from the

battery before recharging.

protection of a secondary 3V battery over a big

range of light strengths (lx).

Three output signals indicate the state of the

system. Power Down (XPD) indicates whether the

supply voltage is high enough to power up and run

the system. Low Battery (LB) is used to signal the

condition when the battery capacity is low and

when to move to power saving mode. The third

signal, SOL, is used for battery charging control.

When the battery is full it bypasses the charging

current by an internal shunt switch to avoid

overcharging. The SW pin can also be used to

control an external shunt switch for higher currents.

To be able to charge a battery also in condition 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
