Abstract:
A system and method for charging a battery. In one embodiment, the system includes a charging circuit that charges the battery with a constant current during a first phase and charges the battery with a constant voltage during a second phase. The system also includes a control circuit for minimizing glitches when the charging transitions from the first phase to the second phase. According to the system and method disclosed herein, a battery may be charged in a controlled and reliable manner.
