Abstract: A method and apparatus for providing telemetry for use in power control functions is disclosed. A system includes an integrated circuit (IC) having a first power management circuit. The IC also includes a number of functional circuit blocks within a number of different power domains. A second power management circuit is implemented external to the IC and includes a number of voltage regulators. Each of the power domains is coupled to receive power from one voltage regulators. During operation, the first power management circuit may send commands requesting the change of one or more voltages provided to the IC. The second power management circuit may respond by performing the requested voltage change(s), and may also provide telemetry data to the first power management circuit. The second power management circuit may also provide telemetry data responsive to receiving a no operation command from the first power management circuit.

Abstract: The switching frequency of a switch mode PFM power converter is compared with a predetermined frequency range that contains the operating frequency of a nearby clocked sub-system. In response to the switching frequency coming into the range, a parameter of the power converter is changed from an original value, so as to cause the switching frequency to go out of the range.

Abstract: A power-management unit is described. This power-management unit allows a common signal line to communicate data between an integrated circuit (which may be external to the power-management unit) and a battery-monitoring mechanism in a battery pack, and to convey a signal that represents a temperature state of the battery pack to a temperature-monitoring circuit or mechanism that monitors the temperature state of the battery pack. In particular, the power-management unit may include a single-wire interface or a multiplexer that, at a given time, selectively couples the signal line from the battery pack either to the integrated circuit or the temperature-monitoring circuit based on a control signal provided by the integrated circuit (for example, via an I2C bus or interface). In this way, the power-management unit may reduce the number of signal lines needed to communicate with the battery-monitoring mechanism and to convey the signal.

Abstract: A method and apparatus for parameter-based sensor selection is disclosed. In one embodiment, a system includes an integrated circuit (IC) having a first power management circuit, and a second power management circuit external to the IC. The IC includes various functional units implemented in various power domains, while the second power management circuit (which may be implemented on an IC) includes a number of voltage regulators for providing power to the power domains. The second power management circuit also includes sensors that provide data about a system parameter, with the data being provided at telemetry to the first power management circuit. When the system parameter is less than a first threshold, the telemetry data may be based on a first sensor. When the system parameter is greater than the first threshold, the telemetry data may be based on a second sensor.

Abstract: A power conversion circuit has multiple phases wherein each of the phases has an inductor coupled to a power switch circuit and is coupled to an output node. A power conversion controller controls the switching of one or more of the phases to yield a regulated voltage on the output node. The controller uses a variable inductor current limit for one or more designated phases, and temporarily increases the variable inductor current limit during a transient condition. Other embodiments are also described and claimed.

Abstract: The described embodiments include a power-management unit that receives and stores a representation of a temperature state of a battery pack from a battery-monitoring mechanism in a battery pack. For example, an interface circuit (such as a single-wire-interface or SWI circuit) may receive the information from the battery-monitoring mechanism via a signal line, and the information may be stored in a memory (such as a non-transitory computer-readable memory). This stored information is then used by a temperature-monitoring mechanism or circuit to determine the temperature state of the battery pack, which may be used to control or gate charging of a battery in the battery pack.

Abstract: A parameter related to the Earth's magnetic field can be used to determine accuracy of a magnetometer of a mobile device. In one aspect, a first instance of a parameter related to Earth's magnetic field is determined using data generated by the magnetometer. The magnetometer data can be based in part on a position of the mobile device with respect to the Earth. A second instance of the parameter can be determined using data generated by a model of Earth's magnetic field. The model data can also be based in part on the position of the mobile device with respect to the Earth. The first instance of the parameter can be compared with the second instance of the parameter. An accuracy metric for the magnetometer can be determined based on a result of the comparison. An indication of the accuracy metric can be presented by the mobile device.
