    Abstract: Devices having battery charge control circuits are disclosed. Such devices can include power control circuits operable to receive electrical power at a connector, and provide power to electrical components, including a charge current for a rechargeable battery; and a controller circuit configured to determine and store a maximum charge current setting based on whether a voltage at the connector falls below a predetermined limit as the charge current is increased. Corresponding methods are also disclosed.

    Abstract: An apparatus includes a rechargeable battery, a circuitry, and a controller. The circuitry is operable to receive power from a power source and to provide power to the rechargeable battery and to other electrical components of the apparatus. The controller is configured to monitor power requirements of the apparatus. Moreover, the controller is further configured to provide power from the rechargeable battery in addition to power supplied from the power source during a peak power event of the apparatus.

    Abstract: Methods for charging a battery of a portable device can include increasing the charge current for the battery, where the charge current sourced from electrical power received at a connector of a portable device. If a voltage at the connector drops below a predetermined value, setting a charge current limit to a level less than that corresponding to the voltage drop. If the voltage at the connector does not drop below the predetermined value, setting the charge current limit to a predetermined level. The charge current limit can be stored, and the battery can be charged with the charge current having a maximum value determined by the charge current limit. One or more application circuits of the portable device can be selectively disabled based on the charge current limit.
