Abstract
According to one exemplary embodiment, a power management unit residing in an electronic device includes a battery detection controller coupled to a battery charger and a regulator block, where the regulator block is capable of providing power to the electronic device. The battery detection controller is configured to turn off the regulator block when the battery charger is coupled to an external power source and is not coupled to a battery of the electronic device. The battery detection controller can be further configured to turn on the regulator block when the battery charger is coupled to the external power source and is coupled to the battery if the battery has a battery voltage greater than a threshold voltage.
