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 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.

Abstract: A circuit may include a switching signal generator to generate a high-side switching signal and a low-side switching signal. A low-side switch may be connected to the output of the circuit and to the switching signal generator to receive the low-side switching signal. A plurality of high-side switches may be connected to corresponding inputs of the circuit. A matrix may be configured to selectively connect the high-side switching signal to two or more of the high-side switches.

Abstract: The present disclosure includes circuits and methods for controlling skin temperature of an electronic device. In one embodiment, a thermal sensor is configured on a case of a handheld electronic device. The thermal sensor is coupled to a battery charger having a current limit circuit. If the sensed temperature of the case increases above a threshold, a current limit is reduced to reduce current in the battery charger.

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.

Abstract: A switching regulator circuit provides forward mode operation where a voltage provided at an input port can be boosted or bucked to produce a regulated voltage at an output port of the circuit. In accordance with the present disclosure, the switching regulator circuit includes two or more input ports. The switching regulator circuit provides a reverse boost operation in which a voltage provided at the output port of the circuit can be boosted to produce a regulated voltage at both of the input ports of the circuit.
