Abstract
A system and method are provided for safely recharging a battery. A current source is coupled to a node and configured to produce a current. The battery is coupled to the node, and is configured to recharge during a recharging cycle based on receiving the current through the node. An overvoltage protection system is coupled between the node and the current source, and configured to disable the current source when a voltage at the node exceeds a threshold value. For example, the current source may be substantially instantaneously disabled when this occurs.
