Abstract: A first portable or non-portable device enters an adaptive charging mode to deliver a programmable output voltage to a second (e.g., sink) device, independent of a connector between the devices. The adaptive charging mode enables a sink device to detect current and voltage capability of the portable or non-portable device. It is determined whether a first device coupled to the second device through a reconfigurable port is configured as a source device or sink device. A current limit of the source device is then detected. A programmable voltage from the source device is requested based on the detecting.

Abstract: Certain aspects of the present disclosure provide apparatus and techniques for charging a multi-stack battery pack. For example, certain aspects provide a circuit for charging a battery pack. The circuit generally includes a voltage regulator circuit and charge pump circuitry having an input coupled to an output of the voltage regulator circuit, and an output coupled to a first battery charging terminal. In certain aspects, the first battery charging terminal may be configured to be coupled to a terminal of a first battery cell of the battery pack having multiple battery cells.
