  • 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.

  • Patent number: 9977091
    Abstract: In one embodiment, a fuel gauge system is described that comprises two or more battery chargers on different integrated circuits (ICs) coupled in parallel to a battery for charging the battery. Each battery charger IC generates a current signal indicative of current generated by said each battery charger IC into the same battery. A fuel gauge is responsible for accurately reporting the battery state of charge, based on a combination of voltage, current, and temperature information.

  • Patent number: 9900056
    Abstract: A system and method providing for delayed initialization of a device in a wireless charging environment. In certain aspects, a device is configured to detect power wirelessly received from a power transmitter. The device may further wirelessly transmit a message to the power transmitter in response to the received power, further determining that a power level of the received power has been adjusted in response to the message. In response to the determining the power level has been adjusted, a controller that is powered by the adjusted power level may be initialized.

  • Patent number: 9843211
    Abstract: Multiple power chargers for mobile terminals are disclosed. In particularly contemplated aspects, a mobile terminal may include two charging circuits arranged serially, such that only one charging circuit charges a battery of the mobile terminal at a time. The serial arrangement allows consolidation of fuel gauge circuitry within one of the charging circuits. In a particularly contemplated aspect, a second charger is tied to a first charger at a system power node. The system power node is further tied to a top port of the second charger. A bottom port of the second charger is tied to a top port of the first charger. A bottom port of the first charger is tied to the battery of the mobile terminal. The fuel gauge circuitry may sense battery current using a known ON resistance of a field effect transistor (FET) of the first charger.
