Abstract: System, methods, and apparatus are described that facilitate signaling between devices over a single bi-directional line. In an example, the apparatus couples a first device to a second device via a single bi-directional line, indicates initiation of a first action, initiated at the first device, by sending a first single transition on the single bi-directional line from the first device to the second device, and indicates initiation of a second action, initiated at the second device, by sending a second single transition on the single bi-directional line from the second device to the first device. In another example, a first device initiates a first action, indicates initiation of the first action by generating a first event on a single bi-directional line, and receives an indication of a second action initiated at a second device by observing a second event on the single bi-directional line.

Abstract: In controlling power in a portable computing device (“PCD”), a power supply input to a PCD subsystem may be modulated with a modulation signal when an over-current condition is detected. Detection of the modulation signal may indicate to a processing core of the subsystem to reduce its processing load. Compensation for the modulation signal in the power supply input may be applied so that the processing core is essentially unaffected by the modulation signal.

Abstract: A method and apparatuses for power regulation using an extended current limit are disclosed. The power regulator detects an occurrence of an output current of the regulator exceeding a first current limit, triggers an extended current limit timer based on the detected occurrence, regulates the output current according to a second current limit higher than the first current limit based on a duration of the extended current limit timer, and regulates the output current according to the first current limit based on an expiration of the duration of the extended current limit timer.

Abstract: Various embodiments include power management system methods including receiving, at a processor(s), a notification signal triggering the processor(s) to implement power usage mitigation at the processor(s), determining, by the processor(s), a mitigation amount of power rail power by which to mitigate current usage at a power rail based on a use case for the power rail, and implementing power usage mitigation at the processor(s) by the processor(s) sufficient to mitigate power usage at the power rail by the mitigation amount of power rail power. Power usage mitigation may include reducing processor(s) current usage: by a predefined amount; proportional to the amount a power rail current exceeds a power rail current threshold; by the amount of current exceeding a processor current threshold; or by a smallest amount between the amount a power rail current exceeds a power rail current threshold and the processor(s) current exceeds a processor current threshold.

Abstract: The present disclosure describes aspects of voltage settling detection for switching regulators. In some aspects, an integrated circuit for controlling a switching regulator includes a modulator having an output coupled to switch drive circuitry of the switching regulator. A digital-to-analog converter (DAC) has a first output coupled to an input of the modulator and a second output configured to indicate when a digital-to-analog conversion is complete. A voltage settling detector is configured to receive, from the second output of DAC, an indication that the digital-to-analog conversion is complete and detect a signal transition at the output of the modulator. Based on the indication and the signal transition, the voltage settling detector can provide a status indication for the switching regulator. By so doing, the voltage settling detector may indicate that an output voltage of the switching regulator is proximate a target output voltage level set by the DAC.
