Solar Cell System Manager

• Power On Indicator

• Low Battery Indicator

• Battery Overcharging

Protection

DESCRIPTION

The solar cell system manager is an analog circuit,

which monitors the supply voltage of a battery-

powered system containing solar cells. The solar

manager uses three output signals to indicate the

state of the system. Power On (PO) 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. It

indicates when the battery is full and the charging

process should be stopped.
