ABSTRACT:
Methods, apparatus, and circuits for managing power among portable computing devices and one or more accessories. One example provides commands to improve power management between a portable computing device and one or more accessories. Other examples provide commands that may allow a portable computing device to charge at a maximum available current level while providing an accessory with sufficient current for its proper operation. Another may help prevent a portable computing device from drawing a high level of current that could be detrimental to an accessory, while others provide commands that may allow a battery pack to instruct a portable computing device to not charge its internal battery. Another example may allow a portable computing device to determine which power supply among multiple power supplies should be used to power an accessory, while others may allow an accessory to retrieve charging current parameters from a portable computing device.
