Abstract:
In one embodiment, a circuit is formed to couple a battery to a charging voltage at least a portion of a time when the charging voltage is greater than zero volts and is less than a first voltage value. The circuit is also formed to decouple the battery from the charging voltage approximately when the charging voltage is greater than the first voltage and also approximately when the charging voltage is no greater than zero volts.
