DESCRIPTION

MAS6011 solar cell system manager monitors the

supply

voltage

of

a

battery-powered

system

containing solar cells. Current consumption of this

IC is extremely low. The solar manager uses three

output signals to indicate the state of the system.

Power Down (XPD) indicates whether the supply

voltage is high enough to run the system. Low

Battery (LB) is used to signal the situation where the

battery is low. The third signal, SOL, is used for

battery charging control. When the battery is full it

bypasses the charging current by an internal switch

to avoid overcharging of the battery.
