  • Patent number: 10432008
    Abstract: The present disclosure includes a method of charging a battery. In one embodiment, the method comprises receiving, in a battery charging circuit on an electronic device, an input voltage having a first voltage value from an external power source. The battery charger is configured to produce a charge current having a first current value into the battery. The input current limit and/or duty cycle of the charger is monitored. Control signals may be generated to increase the first voltage value of the input voltage if either (i) the input current limit is activated or (ii) the duty cycle reaches a maximum duty cycle. The charger also receives signals indicating a temperature inside the electronic device and generates control signals to decrease the value of the input voltage when the temperature increases above a threshold temperature.

    Abstract: A configurable charge converter may include an adaptive low-dropout regulator. The adaptive low-dropout regulator may include a headroom detection circuit and a power supply controller. The headroom detection circuit may monitor a voltage drop across a field effect transistor (FET) and cause a programmable power supply to increase or decrease an output voltage accordingly. In some aspects, the configurable charge converter may include an adaptive low-dropout regulator and a buck/boost converter. The output power of the configurable charge controller may be provided by the adaptive low-dropout regulator, the buck/boost converter, or by both the adaptive low-dropout regulator and the buck/boost converter operating in combination.

  • Publication number: 20180074564
    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.
