    Abstract: A multipath charger includes a first charging path, a second charging path, and a management module. A supply voltage is coupled through the first charging path and the second charging path to a battery. The management module provides the supply voltage and detects the operating state of the battery. The management module selectively enables the first charging path, the second charging path, or both according to the operating state of the battery, so as to charge the battery through the enabled charging path.
