Abstract
In one exemplary embodiment, a control circuit includes a comparator circuit that compares a solar cell voltage and a battery voltage and responsively activates a charging control signal if the solar cell voltage is greater than the battery voltage. If the solar cell voltage is not greater than the battery voltage, the comparator circuit deactivates the charging control signal.
