Abstract: An initial SoC curve may be defined that relates system state of charge (SoC) as a function of battery SoC. Endpoints that define the SoC curve may be updated. For example, each time a battery SoC is determined, the SoC curve may be updated. The SoC curve may then be evaluated to produce a system SoC that can be present to the user.

Abstract: A system for estimating battery state of charge (SoC) includes evaluating a battery model to produce an estimated battery voltage using a previously produced SoC. Current and voltage measurements are combined with the estimated battery voltage to produce a present battery SoC. The battery model may be updated by taking battery measurements when certain conditions occur.

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: A multi-phase charging circuit comprises a device that can be configured for master mode operation or slave mode operation. In master mode operation, the device generates a control signal and a clock signal to control operation of a switching circuit for generating charging current. In slave mode operation, the device receives externally generated control and clock signals to control operation of its switching circuit.

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.
