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.
